Ballast Resistor Replacement & Labor Prices

Ballast Resistor: What It Is and How to Perform a Replacement

A ballast resistor is an important component in older vehicles equipped with points-based ignition systems. Its main role is to limit the voltage to the ignition coil, preventing excessive current that could damage the system. If your ballast resistor is faulty, your car’s engine performance may suffer.

When your ballast resistor is malfunctioning, you may experience engine misfires, starting issues, or electrical problems. Replacing it is relatively simple if you follow the correct steps. Here is how you can perform the replacement:

How to Replace a Ballast Resistor: Step-by-Step Guide

• Step 1: Ensure the engine is off and the battery is disconnected for safety.
• Step 2: Locate the ballast resistor (typically near the ignition coil or on the firewall).
• Step 3: Disconnect the wiring from the ballast resistor and remove it from its mount.
• Step 4: Install the new ballast resistor in the same location and reconnect the wiring.
• Step 5: Reconnect the battery, start the engine, and check if everything is functioning properly.

By replacing the ballast resistor yourself, you can save on labor costs and ensure your ignition system is in top condition. However, if you’re unsure about doing this yourself, it’s always a good idea to seek professional help.
