The internal combustion engine got a starter motor that needs to engage. And that happens when there’s an actuation of a starter solenoid. It stays connected with the starter motor for control. A few more pointers to know are:

Its main job is working as a contactor’s actuating coil, something made for huge electric currents.

This is also related to the connection between the battery and the starter motor.

And that’s one basic introduction to starter solenoid we wanted to give before starting this guide for the Kohler starter solenoid wiring diagram mainly.

But it won’t be the demonstration alone, we will put more details. So that you get to know all you need about the topic.


Here’s The Kohler Starter Solenoid Wiring with Easy Breakdown

The starter relay is another name for the part and for certain vehicles it’s reserved for a separate relay. About the location of the starter motor solenoid, it stays right above the starter motor.

A heavy cable is there for connecting the left side situated threaded terminal with the battery. You should be able to see a linkage on the solenoid coil’s right side. It stays inside a housing. And the job is to engage a pinion that should be seen on the motor’s right side in the housing.

Now to the diagram of Kohler starter solenoid wiring

So, you should get a basic idea about the wiring of Kohler starter solenoid. But in case you didn’t, here’s some explanation that should help.

There are 4 terminals in a starter solenoid. You will find 2 two tiny pin-type terminals. These are referred to as C and D in the diagram above. And there should be two thick bolt-style terminals. Those are referred to as A and B in the diagram.

Elaborating The Parts, a Bit

If you are an absolute novice in this matter, hope this segment gives you a better understanding.

The battery is a part used for starting a motor vehicle by providing electric current. And that triggers the internal combustion engine for propelling vehicles.

Then there’s the Kohler starter motor, which should not be confused with the starter solenoid by the way. This device basically cranks the engine. The system features a solenoid attached that needs to make sure power from the battery is delivered to the starter motor.

Then there’s the ground, people refer to it as earth as well. This is a very crucial part of an electrical system without which there’s no functioning electricity. A battery comes with a negative terminal, which actually is a sort of ground. There are several wires in the engine bay that screw with bare metal only, these are also ground. It is a point that works as a conductor between positive and negative terminals.

There’s a start switch button through which the engine gets noticed for starting by the driver.

Signs of Bad Starter Solenoid in Kohler Riding Mower Engine

You can actually determine whether your Kohler riding mower engine got a worn-out or damaged starter solenoid. And it’s rather simple if you have a few tools at hand. You need a metal screwdriver, a jumper cable, a voltmeter, medium grot sandpaper, a wrench set, and a battery charger.

Here’s How To Check

For Your Information – Certain Kohler engine models have a certain type of starter that uses both starter motor and solenoid as integrated and inseparable units. So, in case of replacement, you need to change the whole thing.

Frequently Asked Question (FAQs)

Can a starter solenoid be repaired?

Burning, carboning up or sticking can happen with a solenoid due to high voltage contacts. And that can make it response with a not starting situation too.
However, in some cases, you can skip replacement and look into repair. But again, that will highly depend on the amount of damage done to the part.

Can you buy just the solenoid for the starter?

A separate purchase might or not be possible. But usually, with a Kohler starter solenoid replacement, you need to get the whole thing together because there will be an addition to the effort needed later on.

Should I replace the starter or just the solenoid?

Before the Kohler starter solenoid replacement, you need to find out if the starter is working fine or not. In case it is having trouble then you must get the whole thing replaced. However, if only the solenoid is facing a problem, repair/replacement of that part alone should help.

How long does it take to replace a starter solenoid?

It will take somewhere between 2 to 4 hours for a typical scene. However, that’s a varying process. So there’s no exact answer to the time needed for the whole replacement.

Can a starter solenoid drain a battery?

Yes, when a starter solenoid gets bad it will drain the battery faster. And that will also compromise the remaining system’s integrity.

Wrapping Up

Now you’ve got the Kohler starter solenoid wiring diagram with its explanation as well as some common signs of identifying the part gone bad. We also tried answering the most commonly asked questions on this matter.

Hope everything, on the whole, will be helpful for you. On that note, we will be leaving for today! Take Care.
