If you own a Chevy vehicle, you might have heard of HEI Distributors. The High Energy Ignition (HEI) Distributor is a popular ignition system that was introduced by General Motors in the 1970s. It is designed to provide efficient and reliable ignition timing. One benefit of the HEI system is that it eliminates the need for external ignition control modules, making it easier to install and maintain.
What is a Chevy HEI Distributor?
A Chevy HEI Distributor consists of a high voltage coil, distributor cap, rotor, and a magnetic trigger. The high voltage coil is responsible for generating the spark that ignites the fuel mixture in the engine. The distributor cap and rotor provide a path for the spark to reach the correct cylinder. The magnetic trigger is used to control the timing of the spark.
The Chevy HEI Distributor is a drop-in replacement for many GM vehicles that came with a points-style distributor. If you’re considering upgrading your ignition system, a Chevy HEI Distributor is a good choice.
Wiring a Chevy HEI Distributor
Wiring a Chevy HEI Distributor can seem daunting at first, but it’s actually quite simple. Before you start, make sure you have the correct tools and safety equipment. You’ll need wire strippers, crimpers, a test light, and safety glasses.
Step 1: Disconnect the Battery
Before you begin wiring your Chevy HEI Distributor, you should always disconnect the battery. This will prevent any accidental sparks or electrical shocks.
Step 2: Remove the Old Distributor
The first step in wiring your Chevy HEI Distributor is to remove the old distributor. This will give you access to the wiring harness and the distributor cap. Make sure you keep track of any wires or components that you remove.
Step 3: Connect the Power Wire
The next step in wiring your Chevy HEI Distributor is to connect the power wire. The power wire is a thick red wire that provides power to the distributor. It should be connected to the positive side of the battery or a fused ignition switch. Use a test light to verify that you have power.
Step 4: Connect the Tachometer Signal Wire
If your vehicle is equipped with a tachometer, you’ll need to connect the tachometer signal wire. The tachometer signal wire is usually a green or white wire that connects to the negative side of the ignition coil. In some cases, it may connect to a dedicated tachometer signal terminal on the distributor cap.
Step 5: Install the Distributor Cap and Rotor
Once you’ve connected the power and tachometer signal wires, you can install the distributor cap and rotor. Make sure you seat the rotor correctly and tighten the cap securely. Check the timing marks on the crankshaft and distributor to verify that the timing is correct.
