Tools Materials
Screwdrivers Wire connectors
Pliers Electrical tape
Wire strippers Starter solenoid
Socket wrench Starter motor

Step-by-Step Guide

Step 1: Disconnect Battery

Before starting any electrical work on your truck, it’s important to disconnect the battery to avoid any potential accidents. Locate the battery and remove the negative cable using a socket wrench or pliers.

Step 2: Locate Starter

The starter is typically located on the passenger side of the engine, near the transmission bellhousing. Once you’ve identified the starter, remove any wires or cables currently connected to it.

Step 3: Install Starter Motor

Take your new starter motor and install it in place of the old one. Secure it using the bolts and nuts provided in the kit.

Step 4: Install Starter Solenoid

Next, install the starter solenoid. This is typically located near the battery or on the firewall. Connect the wires to the solenoid using wire connectors and electrical tape.

Step 5: Wire Starter

Finally, it’s time to wire the starter. Connect the positive cable from the battery to the starter solenoid. Then, connect the “S” terminal on the solenoid to the ignition switch using a wire connector. Connect the “I” terminal to the ignition coil or ballast resistor.


What if I don’t have a starter solenoid?

If your truck doesn’t have a starter solenoid, you’ll need to install one before wiring the starter. This is an essential component that controls the flow of power to the starter motor.

What if I’m not sure which wire goes where?

Consult your truck’s wiring diagram or a manual for guidance. If you’re still unsure, it’s best to seek the help of a professional mechanic or electrician.

Can I use any type of wire connectors?

No, it’s important to use wire connectors that are suitable for your truck’s wiring gauge and type. Using improper connectors can cause electrical issues and potentially damage your starter.

What if my truck still won’t start after wiring the starter?

Check all connections and ensure they’re secure and properly wired. If everything looks good, it’s possible there may be an issue with your starter or ignition system. It’s best to seek the help of a professional mechanic to diagnose and fix the issue.

How long does it take to wire a starter?

The process can vary depending on your level of experience and the condition of your truck. However, typically it takes anywhere from 1-3 hours to wire a starter correctly.

By following these steps and guidelines, you’ll have your 1986 Chevy truck starter wired and ready to go. Remember to take your time and double-check all connections for a smooth and successful start-up. Happy trucking!
