For those who are into cars, you might have heard of HEI distributor. It stands for High Energy Ignition distributor, which is considered one of the best ignition systems in the market. It is known for its reliability, durability, and overall performance. However, installing and wiring the HEI distributor can be a bit challenging, especially for those who are new to it.
In this article, we will discuss the wiring diagram for HEI distributor in detail. We will also answer some frequently asked questions about HEI distributor to help you understand it better.
What is HEI Distributor?
HEI distributor is an ignition system that was developed by General Motors in the early 1970s. It is a breakerless ignition system that uses electronic components to control the ignition timing and voltage. It is designed to provide a high-voltage spark to the spark plugs, resulting in improved engine performance, better fuel efficiency, and decreased emissions.
HEI distributor consists of three main components: the distributor cap, the rotor, and the ignition coil. The distributor cap is made of plastic and houses the rotor and the spark plug wires. The rotor sits on top of the distributor shaft and rotates as the engine runs, making contact with the distributor cap’s metal contacts, which are connected to the spark plugs.
The ignition coil is mounted on top of the distributor cap and generates the high-voltage spark that travels down the spark plug wires to ignite the fuel mixture in the engine’s cylinders.
Wiring Diagram for HEI Distributor
The wiring diagram for HEI distributor is relatively simple compared to other ignition systems. The HEI distributor has two wires that need to be connected: the red wire and the white wire. The red wire connects to the positive side of the ignition coil, while the white wire connects to the negative side of the ignition coil.
Here is a step-by-step guide on how to wire your HEI distributor:
- Disconnect the battery to prevent any accidental electrical shock or damage.
- Remove the distributor cap and rotor.
- Identify the two wires on the distributor: the red wire and the white wire.
- Connect the red wire to the positive side of the ignition coil.
- Connect the white wire to the negative side of the ignition coil.
- Reinstall the distributor cap and rotor.
- Reconnect the battery.
- Start the engine and check for any issues.
It is important to follow the wiring diagram properly to ensure that the HEI distributor is installed correctly. Any mistake in the wiring could result in engine damage or misfire.
