The starter motor cranks the engine to get it going—you know that much. But do you truly understand how the starter and the rest of the starting system work.

The positive cable links the starter solenoid to the (+) battery terminal. Meanwhile, the negative or ground cable connects the transmission or engine cylinder block near the starter to the negative (-) battery terminal.

The starter, which operates with the help of a solenoid, can generate a significant amount of horsepower for a limited time. On most vehicles, the solenoid is mounted on top of the starter.

Both designs operate in a similar manner: Once an air-fuel mixture and spark are added to the equation, the engine begins to run.

If the driver fails to do so, the starter has a one-way clutch that will allow it to freewheel. That way, the starter doesn’t get damaged by the spinning engine.

With a direct-driver starter, the starter motor and gear turn at the same speed on the same shaft. With a gear-reduction starter, the starter gear has more torque despite spinning slower than its counterpart in a direct-drive setup.

Gear-reduction starters are smaller, lighter, and more efficient than their direct-drive counterparts, helping batteries last longer. Now you know how a starter motor works.

Starting circuit operation is fairly straightforward. When the driver turns the key to the “start” position in a typical starting system, battery voltage flows from the ignition switch to an underhood relay.

The solenoid then engages the starter to crank the engine. It’s worth noting that, on many modern vehicles, the ignition switch and neutral safety switch (or clutch safety switch) are not wired directly into the starter circuit.

The BCM and TCM communicate the position of the switches to the engine control module (ECM) over a data network. If the conditions are correct, the ECM then operates the starter relay to supply power to the starter solenoid.

Typically, a starter-mounted solenoid has three terminals with three connections: When the driver turns the ignition key to the “start” position, voltage is sent to the starter’s “S” terminal.

The windings then create a magnetic field that pulls the starter’s plunger, forcing it to push a disc against a set of contacts. Those contacts attach to the solenoid’s “B” and “M” terminals.

A licensed mechanic is your best source of information about wiring a starter. If you want to learn more but don’t have time to stop by your auto repair shop for a consultation, you might find the answers to these questions helpful.

Two cables usually connect the battery to the starter: a red wire and a black or greenish-yellow one. The red wire connects the battery’s positive terminal to the solenoid, while the other cable connects the battery’s negative terminal to the motor.

Yes, you can. It’s one of the ways mechanics check starters.

First, they turn off the ignition and put the transmission in park mode. Then, they connect one end of the positive cable to the battery’s positive terminal and the other end to the starter motor’s positive terminal.

For example, if the starter cranks the engine, there might be something wrong with the cables or relay. A high electric current might surge through the solenoid due to faulty control or starter circuit connections.

Your car will struggle to start if there’s loose ground to your starter. A starter ground cable often goes from the starter housing to the transmission case and the engine block.

Your vehicle might not be firing up due to a bad starter if you notice these telltale signs: Check out this guide to learn what causes each bad starter symptom.

Are your mechanic bills spiraling out of control.

Unfortunately, many modern vehicle owners lack the basic knowledge of how a car functions.

Or Are you aware of how to wire a starter solenoid.

Below is Cloom’s DIY guide on the starting system.

Diagram showing a car starter system. Although technology has changed much of what is in a car, the ignition components are still more or less the same.

For your engine to start, it needs a high current which usually comes from your car’s battery.

When you look at your car battery, you usually see two cables.

First, the red one connects the starter solenoid to its positive terminal.

Then, a black or greenish-yellow cable connects the starter motor to the battery’s negative terminal. Car starter relay.

That is, it’s responsible for igniting the starter solenoid so your car can start.

As such, you can use the battery power for other things, such as using your power windows and car radio without cranking the engine.

Assorted Car Starter motors. The starter motor is the reason why your car’s engine starts.

It’s usually around where your car’s engine is, but it could also be a separate unit like in BullDozers.

neutral safety switch. A neutral safety switch prevents your car from jerking when the engine starts.

The neutral safety switch usually works the same in automatic and manual cars, using your car’s PCM inputs to engage.

The starter solenoid has two functions in your car’s starting system.

Then, it engages the starter gear to the engine flywheel facilitating it to crank up. Start the engine.

Next, the starter solenoid pushes the motor gear to engage with your engine’s flywheel.

You should also know that the starting system only works when the car is in Neutral or Park.

Do you know that most problems are related to the solenoid.

Most cars produce a clicking sound right before an engine starts.

So, failure to hear this sound when powering your car indicates a problem with one of the two. Any rapid noises from your vehicle or show that something is wrong.

For example, if your car keeps clicking rapidly with each start, you have solenoid problems.

So, before you rush to replace your solenoid, check your battery and alternator first. Engine cranking is a fast motion that only takes a few seconds.

Yet, sometimes your car sounds like it is struggling to get going.

But, if the issue persists after jumping the power source, the chances are that you have a solenoid with burnt contacts.

Finally, you know you must replace your solenoid when your engine doesn’t start.

The first opinion is to check for poor connections.

Starter solenoids come in two types.

Or, you can also opt for a remote-mounted solenoid.

Additionally, they feature a single coil spring return and come with SIL 2 & 3 certification. Furthermore, they can either feature a 3-pole or 4-pole solenoid switch.

The procedure is different when you use either pole. on-starter solenoid.

The main difference between a 3-pole starter solenoid and a 4-point starter solenoid is how they work and their connection to the field coil.

On the other hand, in 3-pole solenoids, the terminals’ primary function is to launch the starter motor. Furthermore, 3-pole solenoids feature a series connection with the field coil compared to the parallel one in 4-pole solenoids.

Thus, 4-pole solenoids can still function with varying battery charges since the NVC and field winding are on different circuits. Below is how you can wire a four-pole solenoid.

However, they do not have a smaller terminal for the ballast resistor or ignition coil connection. Cloom recommends using an AWG 4 gauge cable for this connection.

It can handle the high voltage electrical connection from your car battery.

Car starter relay. Starter solenoids and starter relays are essential parts of any vehicle’s ignition system.

They need regular maintenance checks and wiring to continue working properly. But no matter what kind of help you need, Cloom is always available to provide you with the best automobile wire harness solutions and guides to ensure your vehicle is always running.

Learn how to write a starter relay is easy. You only need a few wiring tools like a pair of pliers, spanners, some wires of appropriate gauge, and a little technical know-how of how the starter relay operates.

The electromagnetism produced moves an armature to complete a circuit that delivers a large current from the battery to the starter motor and the starter solenoid.

Two to cater for the large amperage from the battery to the starter solenoid, and the two that receive the low amperage from the ignition switch circuit. Looking at a T&X® starter relay above, these terminals are highly visible.

The bolts help secure the wire connectors into place. Some starters will have three terminals only, two big ones and one small terminal.

When the starter relay is mounted, the bolt securing it acts as the earth connection.

Step 1. Before beginning, make sure the cable connected to the positive terminal of the battery is disconnected and securely out of the way to avoid electrical accidents.

The relay usually comes with extensions to its casing with openings through which to slip mounting screws. If it doesn’t, finding a way to mount it should be easy.

Next, locate the wire that goes to the starter solenoid and connects it to one of the big terminals on the starter relay. It doesn’t matter which terminal you use, just choose one of the two.

This wire will be carrying a high current to the starter solenoid and should be of the right thickness. If there’s no wire already connected and you have to use yours, make sure you connect it to the terminal marked S on the starter solenoid.

Step 3. Find the thin pair of wires from the ignition switch circuit.

This is the wire that will be carrying low current from the ignition circuit to the coil winding of the starter relay. It’s, therefore, not very thick.

In case the starter relay has 3 terminals only, connect the thin wire to one of the bolts that secure the relay to the body of the car. Or just anywhere, provided it touches the casing of the starter relay.

Step 4. Finally, find the wire leading the positive terminal of the battery.

If the wire is not available, use yours and connect it to the positive terminal of the battery. Use the right gauge for the wire, because it will be carrying a large current from the battery.

In the end, you need to test your starter relay wiring, to see if it’s right. Get into the driver’s seat and switch on the ignition circuit to see if the engine cranks and comes to life.

When starting a vehicle, different parts are involved. One of them is the starter relay, a small but crucial component of the starting system.

Some websites even contain information that says so. However, that is not true.

The starter relay switches on the current that activates the starter solenoid. The starter solenoid, on the other handed, closes the switch for the starter motor and usually mounts on the motor.

This guide contains information about the automotive starter relay. In it, you will find all there is to know about the starter relay: what it is, its location in a vehicle, how it works, and its function.

Starter Relay Replacement Process. Chapter 1.

A starter relay is a small, electrical device found in the starting circuit of high-current motors. The relay is essentially a remote switch that controls a high-current circuit.

In some automotive applications, the starter relay works together with the starter solenoid to operate the starting system. In others, the ignition switch operates the starter solenoid circuit directly.

Apart from cars and trucks, starter relays can be found in many other applications where electric motors are involved. These include motorcycles, refrigerators, lawnmowers, and more.

The starter relay in bikes works the starting circuit much similar to how a car starter functions.

That could possibly arise from the fact that both act as relays. But contrary to what some people think, the two names do not mean the same vehicle part.

Here are the ways these two auto parts are different.

It essentially comprises a magnetic core with a wire wound around it. On one end of the core is an armature or plunger that closes contacts to work a switch.

A starter solenoid is usually bigger than the starter relay. The solenoid’s internal construction consists of two coils of wire and a magnetic core towards one end.

The other end is where current enters the solenoid and contains the various connectors. Both the starter relay and starter solenoid operate almost identically.

In a starter relay, the magnetism moves an armature or plunger to close a circuit. In a starter solenoid, the magnetic force created by current flowing through the coil causes the core to move out.

It closes contacts that switch on the starter motor. It also moves the pinion gear to engage the flywheel.

The starter solenoid, on the other hand, both closes a circuit and moves a gear to act as an actuator. The starter relay is usually mounted a far distance from the starter motor, while most starter solenoids attach to the motor housing.

Here is how. For the engine to start, it has to receive torque from outside.

Now, the starter motor used in most vehicles is a power-hungry device. To start spinning, it can draw from a few to many amps depending on vehicle type and make.

The ignition switch comprises delicate parts and very thin wires. If the amount of current required by the motor were to pass through it, a lot of damage would occur.

The starter relay prevents this from happening by allowing the starter current to bypass the ignition switch. Were it not for the relay, the ignition switch would need to be made of large parts and thick wires.

It would also be expensive to make automobiles with big ignition switches and corresponding wire sizes. A relay eliminates these challenges and manufacturing costs.

It allows a large current to flow when you turn the ignition key or press the start button on your car. The ignition switch cannot handle the large current required by the starter motor.

As we have seen, doing away with the relay would mean a large ignition switch and thick wires, both impractical solutions in a typical automobile. If the starter relay is not working, it can mean a vehicle that will not start.

They also require different solutions depending on the type and extent of the damage. There are those that can be repaired and others that need a new relay installed.

The starter relay location may vary depending on the vehicle type and model. It can be in the fuse box (also called a power box), the fuse panel under the dash, or on the right fender.

Often called the fuse box, this is where a vehicle’s fuses and relays are mounted. The box is usually installed on the driver’s side.

In that happens, we recommend that you use your car’s manual. It will have the identity of every component in the box.

When mounted in the fuse box under the dashboard, a starter relay may not be easy to locate, or even comfortable to remove. Starter relays that attach on the fender wall may not be difficult to find.

If unsure, the vehicle manual can be used to confirm the location of the starter relay. The starter relay is made up of different parts, some moving and others immovable.

how it looks like and its internal construction. That will help you to understand how it works better.

Chapter 2.

However, they operate the same way and perform a similar function. Looking inside these components, you will realize that they have identical parts.

The internal construction forms an electromagnetic switch that a driver operates remotely when starting a vehicle.

Fuse box starter relays are a box construction, with pins or connectors protruding from the housing. Behind the connectors are the internal components, which consist of an electromagnet, armature or plunger, and contacts.

Fender-mounted starter relays are mostly the cylinder types. They are a basic construction with only four connection points.

Unlike the fuse box types, fender-mounted starter relays only use two connectors for the primary or coil side. Here are pictures showing the two kinds of starter relays.

The main parts of a typical starter relay include. Armature– this is the part that gets by the iron core when current passes through the coil windings.

Spring– the spring tensions the armature, allowing it to return to the original position when the ignition switch is turned off. Without the spring, the relay might keep the contacts together, causing the starter to operate for longer than is necessary.

As a result, it creates a magnetic field to cause the iron core to become magnetized and move the armature or plunger. Iron core– the iron core magnetizes when the coil would around it is energized.

2006 Aveo 1.6L I had to replace the engine to heater core hose as it had broke by the clamp near the engine, which required removing the starter. I was in a rush considering I was/am laying in snow putting this car back together, and forgot the wire placement on the starter.

On the right hand side of that solenoid another wire is attached…where is that wire coming from (harness). I’m looking all around for it but can’t seem to locate where it went after I removed it.

On the flip side, the removal of the engine to heater core hose was as follows: 1. Remove battery 2.

Reduce antifreeze level and remove hoses going to reservoir box and place out of the way from the egr valve tube. Disconnect the egr valve and place wire aside.

Before your engine turns and starts, when you enter the car and start your car, a series of steps are required. The starter relay is one of the most critical and often overlooked components in any vehicle ignition system.

The relay is just a remote control switch that regulates the current in a high-current circuit. The starter relay in the car uses a moderate ignition switch current to close the much more powerful starter circuit.

A starter solenoid circuit can be controlled directly by an ignition switch in some cases. These are usually small vehicles and the starter motor does not require a lot of current to run.

We also include information about the sign of a bad start relay, how to test it, and how to replace or repair a bad start relay. continue reading.

How to test the symptoms of a bad starting relay. Between the vehicle’s battery and the starter motor, the starter relay acts as a circuit completer or circuit breaker.

According to the description, this is a switch between the start solenoid and the start motor. When you turn the ignition key or press the car’s start button, a large current is generated.

If there is no relay, it will burn out. If the starting relay fails, the vehicle may not start.

They also require various treatments according to the nature and severity of the hazard. Some can be repaired, and some require the installation of new relays.

When you turn on the ignition switch, your key activates the starter relay, which sends power to the starter solenoid, and the solenoid sends power to the starter motor. When you turn on the ignition key, the starter relay transmits small power to the starter solenoid, and the solenoid draws a large current directly from the car battery.

All modern launchers follow this procedure. In order for the starter to engage and turn the flywheel, power is sent to the starter relay via the solenoid.When starting your car, the starting relay is essential.

The location of the start relay varies by vehicle type and model. The fuse box (also called the power box), the instrument panel under the fuse panel, or the right fender are all possible locations.

This is where car fuses and relays are installed. It is also called a fuse box.

Wires go in and out of the relay. However, many other relays have similar appearances in cars.

It may not be difficult to locate the starting relay attached to the fender wall. These relays are usually cylindrical and can be identified by their mounting posts and leads.

The starter relay, like other mechanical and electronic components in your car, will show signs of failure before it finally stops. Some signs of damaged or worn starter relays are listed below.

When we turn off the ignition switch, both the starting solenoid and the motor should stop working. When the starter relay doesn’t operate in this order, the engine won’t start.

If this happens, the starter relay will be trapped in the start position, causing damage to the starter, circuit, relay and drive flywheel, if not dealt with immediately.

The failure of a car to start is one of the most obvious signs of a car breakdown. Although many potential failures may prevent the car from starting, the failure of the starting relay is often the source of the problem.

When you turn the ignition key, your battery is shaken, releasing a burst of electrical energy. The starter motor is triggered by this energy and turns your engine.

A defective starter relay will prevent your battery from delivering electrical signal to your starter motor. Therefore, no matter how many times you turn the key, your engine will not start.

In either case, you should get professional help to evaluate the symptoms and accurately diagnose the cause. 2)The start relay remains open after the engine is started.

When we turn off the ignition switch, both the starting solenoid and the motor should stop working. The main contacts of the starter relay are probably already welded together, in the closed position, if it does not operate in this order, the relay keeps the engine started.

It usually happens when the relay touches anything or is exposed to a lot of electricity. Because this problem may damage the entire boot system, it must be diagnosed and dealt with immediately.

Relays usually operate on an all-or-nothing basis. It either sends the entire current, or it sends nothing.

The starter relay makes a clicking sound, but the engine does not rotate, which indicates that the starter motor is not receiving enough current from the relay. This may also be a sign of low or exhausted battery power.

Smaller power may damage the entire starting device or cause the vehicle to fail to start, accompanied by annoying clicking sound. Both of these conditions may be caused by corroded or aging relays with damaged contacts.

Scrape the corroded surface of the relay with sandpaper or a gravel scraper. You can replace the relay to get a larger output, or you can contact a professional mechanic.

When the starter relay is working, it transmits power to the starter every time it is turned on. However, debris, dirt and high temperatures can contaminate this ingredient.

Due to these conditions, the starting relay may be forced to work intermittently. The starter relay is the basic component of the ignition system and has very few moving components, which is why it rarely fails.

If the relay is not malfunctioning, there may be a damaged or corroded wire connection under the hood.

Tool: Safety glasses and gloves.

Ensure that the car is parked safely and the transmission is in neutral or parked state. When working under the hood, you don’t want the vehicle to move forward accidentally.

Before testing, prepare a fully charged battery and a portable jumper. Or, you can check your car battery to make sure it is fully charged and not the source of your problem.

Step 3. Check the connection terminals on the battery and starter.

Before cleaning corroded terminals, disconnect the negative battery cable and set it aside. Remove the battery positive cable from the battery and set it aside.

Use baking soda, water and a wire brush to clean the rusty terminals. If necessary, clean the starter terminal.

Step 4. The cable from the starting solenoid to the starting relay should be followed.

Two smaller wires are used to “turn on” the relay and come from the critical switching circuit. Two larger wires connect from the battery to the starter, carrying the battery voltage.

Connect one end of the jumper wire to the chassis ground. Terminal 86 should be connected to the other end.

Connect a jumper wire to the positive terminal of the battery. Since the connection between the battery and the starter has been cut off, the jumper can be connected for a short time.

Its resistance should be less than 1 ohm. If.

by: Alittle1, Cobalt327, Jon(Click here to edit this page anonymously, or register a username to be credited for your work.). Sometimes a modified vehicle- especially one that uses headers- will experience starter “drag” when the engine is hot, which is akin to having a low battery even though it’s fully charged.

If the ignition (especially the timing), electrical, starting and charging systems are otherwise adjusted and working like they should, the problem may be “heat soak”. Heat soak is a condition where the heat from the engine and exhaust system heats up the starter, solenoid, and wiring which causes an increase in resistance.

The following changes will help this situation by removing the relay function of the starter solenoid to a cooler part of the engine compartment.

Also when the battery is trunk-mounted, it’s a good idea to use a remote Ford solenoid/relay. This will keep the run of heavy cable from the battery up to the starter from being always “hot”.

If for some reason you want to keep your vehicle all GM, use a Standard p/n U939 solenoid like the one pictured below. They were used in some GM powered motor homes:.

The battery wire to the solenoid in the stock configuration is hot at all times. The sequence of events that happens in the standard GM when you hit the starter is as follows.

Here is where a problem is encountered. It takes a fair amount of current to energize the stock solenoid when hot.

This is where the Ford solenoid comes into play.

The wiring has to be in good condition. This means no frayed wiring, tight high quality terminals, no wires of insufficient size, no parts store clamp-on replacement battery terminals (the #1 cause of “bad starters”).

Throughout the electrical system there needs to be tight connections, a properly working charging system including the battery, and a good starting system. Grounds have to have direct contact with bare metal and be of a sufficient gauge for the job.

If the problem remains even after the remote Ford relay/solenoid is installed, a starter heat shield may help. Another option is a “permanent magnet” starter.

Then there’s the heavy duty “high torque” mini starters- also permanent magnet type starters.

This often happens when there is a big cam that needs a lot of initial advance or needs the timing locked at full advance.

Generally the switch is a momentary on-type switch that is installed in positive wire to the ignition coil. This will allow the engine to be turned over by the starter, without the ignition being armed.

Diagnosing a faulty ignition wire to the starter solenoid can be a tricky process (not once you understand what wires go to the starter solenoid). To ensure that the problem is accurately identified and resolved, it is important to follow certain steps.

A starter solenoid is an electromechanical device that is used to control the flow of electricity in a car’s starting system. It acts as a switch between the battery and the starter motor, allowing the engine to start when you turn the key in the ignition.

If you are looking for ways to improve how well-maintained and efficient your car runs, then this upgrade should definitely be considered as part of a regular maintenance routine for optimal results. Ignition wires and starter solenoids are essential components of a vehicle’s electrical system.

Unfortunately, these parts can be prone to problems that can cause the engine to fail to start or run erratically. One common problem with ignition wires is corrosion or wear on the metal connectors at either end of the wire.

To fix this issue, it is necessary to replace any corroded or worn connectors with new ones. Another common problem with ignition wires is a break in one of the internal conductors inside the insulation sheath.

If this happens, it will prevent current from flowing through that particular wire and result in an intermittent spark delivery or no spark at all when attempting to start the engine. To fix this issue, it is necessary to replace any broken wires with new ones that are properly insulated for protection against further damage from road debris and other sources.

One such issue is a faulty starter relay switch which prevents current from flowing through the solenoid when attempting to start an engine by turning over its crankshaft via a keyed ignition switch position (e.g., “start”). Although, make sure you’re aware of the ignition switch replacement cost, as well as what wires go to the ignition switch, and how to test the ignition switch.

In addition, starter solenoids may become stuck due to corrosion on their internal contacts which prevents them from engaging when attempting to turn over an engine’s crankshaft via a keyed ignition switch position (e.g., “start”). In such cases, replacing any corroded contacts should resolve this issue so long as there are no other underlying issues causing it (e.g., faulty wiring).

Installing an ignition wire to a starter solenoid is a relatively simple task that can be completed in just a few steps. Before beginning, it is important to ensure that the battery has been disconnected and all safety precautions have been taken.

Locate the starter solenoid on the vehicle and identify the positive terminal, which will be marked with either “B+” or “S” for a starter. 2.

Make sure that it is securely attached so that it does not come loose during the operation of the vehicle. 3.

Securely attach this end of the wire using another nut and bolt or other appropriate fasteners at its destination point, ensuring that it is firmly connected so as not to come loose during the operation of the vehicle again. 5.

If there is no continuity present then check all connections for tightness before attempting further troubleshooting steps if necessary. Replacing an ignition wire and starter solenoid is a relatively simple task that can be completed in a few steps.

This article will provide an overview of what you need to know about replacing an ignition wire and starter solenoid. In conclusion, replacing an ignition wire and starter solenoid requires some basic knowledge of automotive systems but can be done relatively easily with some patience and attention to detail on behalf of those attempting it themselves at home without professional help required in most cases.

This terminal is usually marked with an “I” or “IGN” and is connected to the positive side of the ignition coil (though, do note the symptoms of a bad ignition coil, as well as the symptoms of a bad ignition control module). The other end of the wire should be connected to a 12-volt source, such as a battery or fuse box.

Maintaining the electrical system of your vehicle is essential for its proper functioning. In this article, we will discuss how to troubleshoot your vehicle’s electrical system by checking the ignition wires and starter solenoids.

Upgrading the electrical system of your vehicle is an important step in ensuring its longevity and performance. High-quality parts, such as ignition wires and starter solenoids, can provide a number of advantages that will help keep your car running smoothly for years to come.

Overall, investing in high-quality ignition wires and starter solenoids for your vehicle’s electrical system provides numerous advantages including improved performance, reduced maintenance costs, enhanced safety features, and increased reliability over time – all factors which contribute towards keeping your car running smoothly for years down the line.

A: The purpose of an ignition wire to the starter solenoid is to provide a connection between the ignition switch and the starter motor, allowing current from the battery to flow through and activate the starter. This connection allows for the easy starting of your vehicle.

I think you’ll be surprised at how easy it is to troubleshoot the starter motor to determine if it’s good or bad. In this tutorial, I’ll explain the three tests you need to do on the starter to determine if it’s good or bad.

NOTE: The starter motor test in this tutorial is an on-car test. The photos I’m using show the starter motor off of the vehicle only to explain the test connections better.

APPLIES TO: This tutorial applies to the following vehicles: TIP 1: Ensure the battery has a full charge before starting any of the tests in this tutorial.

TIP 3: Read the entire article first to familiarize yourself with the tests. TIP 4: Use jack stands for safety.

TIP 5: Take all necessary safety precautions. Use safety glasses while working underneath the vehicle.

A starter motor that is malfunctioning will cause one of two problems: NOTE: It’s important to remember that if your vehicle has an intermittent engine no-crank issue, the starter motor will need to be checked or tested when the no-cranking issue occurs.

Here’s a list of the things you’ll need: The starter motor receives a 12 Volts activation signal when you turn the key to crank and start the engine.

In this second test section, we’ll apply 12 Volts directly to the starter solenoid S terminal. The purpose of this test is to bypass the 12 Volts enable signal from the ignition switch and see if the starter motor will activate and crank the engine.

You can purchase or rent this tool at your local AutoZone or O’Reilly Auto Parts store. You can see an example of a remote start switch and where to buy it here:

If your Chevy S10 (GMC Sonoma) is equipped with a standard transmission, place it in neutral. OK, let’s get testing:

Disconnect the battery negative (-) terminal. You’ll reconnect it back in one of the following steps.

Attach one end of the remote starter switch to the battery positive (+) post. Attach the other end of the remote starter switch to the S terminal of the starter motor solenoid.

Also, in case you’re wondering, you can leave the starter motor solenoid’s S terminal wire connected to the engine’s wiring harness connector or not, the test will work either way. Reconnect the battery negative (-) cable to the battery negative post.

You’ll get one of two results: 1.) The starter will activate and will turn over the engine. 2.) The starter motor won’t do a thing.
