3 Pole Starter Solenoid Wiring Diagram: Everything You Need To Know


If you’re looking to wire a 3 pole starter solenoid, you’ve come to the right place. In this article, we’ll take a deep dive into the world of starter solenoids and explore everything you need to know about wiring them up.

What is a Starter Solenoid?

Before we dive into wiring, let’s first define what a starter solenoid is. A starter solenoid is an electromechanical device that controls the flow of electrical current to the starter motor in a vehicle’s engine. It essentially acts as a switch, allowing the battery to send power to the starter motor and crank the engine.

Types of Starter Solenoids

There are two main types of starter solenoids: 2 pole and 3 pole. A 2 pole solenoid has two connections – one for the battery and one for the starter motor. A 3 pole solenoid, on the other hand, has an additional connection for the ignition switch, which allows the solenoid to be controlled remotely.

Why Use a 3 Pole Starter Solenoid?

So, why use a 3 pole starter solenoid instead of a 2 pole solenoid? The main advantage of a 3 pole solenoid is that it allows for remote starting. By connecting the ignition switch to the solenoid, you can start the engine from a distance, which can be useful in certain situations.

Wiring a 3 Pole Starter Solenoid

Now that we’ve covered the basics, let’s get into the nitty-gritty of wiring a 3 pole starter solenoid. Here’s a step-by-step guide to help you get started:

Step 1: Gather Your Materials

Before you start wiring, you’ll need to gather a few materials. Here’s what you’ll need: – A 3 pole starter solenoid – Electrical wire (16-18 gauge) – Wire stripper/crimper – Electrical tape

Step 2: Disconnect the Battery

Before you start working on any electrical components, it’s important to disconnect the battery to avoid any potential electrical shocks.

Step 3: Locate the Starter Solenoid

Next, locate the starter solenoid in your vehicle. It’s typically located near the battery or the starter motor.

Step 4: Identify the Connections

Identify the three connections on the solenoid. They are typically labeled “Battery”, “Starter”, and “Ignition”.

Step 5: Wire the Battery Connection

Using the electrical wire and wire stripper/crimper, connect one end of the wire to the positive terminal of the battery and the other end to the “Battery” connection on the solenoid.

Step 6: Wire the Starter Connection

Using another piece of electrical wire, connect one end to the “Starter” connection on the solenoid and the other end to the starter motor.

Step 7: Wire the Ignition Connection

Finally, using a third piece of electrical wire, connect one end to the “Ignition” connection on the solenoid and the other end to the ignition switch.

Step 8: Test Your Wiring

Once you’ve wired everything up, it’s important to test your wiring to make sure everything is working properly. Reconnect the battery and turn the ignition switch. If the engine cranks, your wiring is working correctly.

Troubleshooting 3 Pole Starter Solenoid Wiring

If you’re having trouble getting your 3 pole starter solenoid to work, here are a few troubleshooting tips: – Make sure all connections are tight and secure. – Check to make sure your wiring is correct – refer to the wiring diagram if necessary. – Test your battery to make sure it’s fully charged. – Test your starter motor to make sure it’s working properly.


Wiring a 3 pole starter solenoid may seem daunting at first, but with the right materials and a little bit of know-how, it’s a relatively simple process. By following the steps outlined in this article, you should be able to wire up your solenoid and get your engine cranking in no time.
