For many auto mechanics, wiring diagrams can be a mystery. Working with a wiring diagram can help make the job easier, but it can also be confusing if you don’t know what you’re looking at. When you’re working with wiring diagrams for the GM HEI distributor, it’s important to understand what each component does.
Distributor Parts
The GM HEI distributor has several parts that are essential for proper functioning. The coil is the main component, which provides the spark for the spark plugs. It also has a breaker plate, which contains the mechanical points. The breaker plate is connected to the crankshaft, which is the rotating part of the engine. Additionally, the distributor has a vacuum advance, which helps regulate the timing of the spark.
Wiring the Distributor
When wiring up the GM HEI distributor, it’s important to pay close attention to the diagram. The wiring diagram should show the different colors of the wires and how they are connected. The most common colors are black and orange, with black being the ground wire and orange being the power wire. Additionally, there will be two wires connected to the coil, which are typically red and white. The white wire is the high voltage wire that sends the spark to the spark plugs.
It’s also important to remember that the GM HEI distributor has a built-in module. This module controls the timing of the spark, so it’s important to connect it correctly. The module will have two wires, which are typically yellow and black. The yellow wire is the power wire, and the black wire is the ground wire.
Conclusion
When wiring a GM HEI distributor, it’s important to understand the wiring diagram and connect the components correctly. Additionally, it’s important to remember that the GM HEI distributor has a built-in module that controls the timing of the spark. By understanding the wiring diagram and the components of the GM HEI distributor, you can ensure that your vehicle is running correctly.
