How to Read HEI Conversion Wiring Diagram?
Reading HEI conversion wiring diagram may seem challenging, but it is quite simple. The first step is to identify the components in the diagram. The components include the HEI distributor, ignition coil, battery, and starter. The wires are represented by straight lines, and their connections are indicated by dots. The wires’ colors are shown next to the lines or dots. The arrows indicate the direction of the electrical current flow. The symbols on the diagram represent the relays, switches, and fuses.
How to Wire HEI Conversion?
Wiring HEI conversion involves several steps. Here is a step-by-step guide:
Step 1: Disconnect the Battery
Before starting the wiring process, you need to disconnect the battery to avoid any electrical shock or short-circuit.
Step 2: Remove the Old Ignition System
You need to remove the old points-and-condenser system from your car’s engine. This involves disconnecting the wires from the ignition coil, distributor, and starter.
Step 3: Install HEI Distributor
Install the HEI distributor on your car’s engine. The distributor should fit the engine’s camshaft and align with the rotor’s position.
Step 4: Wire the HEI Distributor to Ignition Coil
Connect the wires from the HEI distributor to the ignition coil. The positive wire from the distributor should be connected to the positive terminal of the ignition coil. The negative wire from the distributor should be connected to the negative terminal of the ignition coil.
Step 5: Wire the HEI Distributor to Battery and Starter
Connect the red wire from the HEI distributor to the positive terminal of the battery. Connect the yellow wire from the distributor to the starter’s solenoid.
Step 6: Ground the HEI Distributor
Ground the HEI distributor by connecting the black wire to the engine block or chassis.
