The Acceler High Energy Ignition (HEI) distributor is a popular choice for automotive enthusiasts due to its easy installation and reliability. However, proper wiring is crucial to ensure optimal performance and longevity of the distributor. In this article, we will guide you through the Acceler HEI distributor wiring diagram.
What is an Acceler HEI distributor?
An Acceler HEI distributor is a type of distributor that uses electronic ignition to generate high voltage sparks for the ignition system. It was first introduced by General Motors in the 1970s and has since become a popular choice for aftermarket ignition upgrades due to its simplicity and reliability.
The distributor consists of a rotor, cap, coil, and module, and is designed to provide a strong and consistent spark for the engine’s ignition system.
How to wire an Acceler HEI distributor?
Wiring an Acceler HEI distributor is relatively straightforward, but it is important to follow the correct wiring diagram to ensure proper operation. Here is a step-by-step guide to wiring an Acceler HEI distributor:
Step 1: Disconnect the battery
Before starting any electrical work, it is essential to disconnect the battery to prevent any potential safety hazards. Locate the battery terminal and remove the negative cable.
Step 2: Connect the distributor
Locate the Acceler HEI distributor and remove the old distributor from the engine. Install the new distributor by aligning the rotor in the correct position and inserting it into the engine block. Connect the distributor’s wiring harness to the module.
Step 3: Connect the coil
The coil is responsible for generating the high voltage spark required for the ignition system. Connect the coil’s positive wire to the distributor cap’s center terminal, and the negative wire to a ground source such as the engine block or chassis.
Step 4: Connect the power source
Connect the distributor’s power wire to a switched 12-volt source, such as the ignition switch, using a 14-gauge wire. It is essential to use a relay to provide power to the distributor to avoid voltage drop and potential damage to the ignition system.
Step 5: Connect the tachometer
If your vehicle has a tachometer, it will need to be connected to the distributor. Connect the tachometer wire to the distributor’s tach output terminal, located on the side of the distributor cap.
