Frequently Asked Questions
What is a 1-wire alternator with internal regulator?
A 1-wire alternator with internal regulator means that the alternator only needs one wire to operate and regulate itself. The internal regulator eliminates the need for an external regulator, making the wiring process simpler.
What is an HEI distributor?
An HEI (High Energy Ignition) distributor is a type of distributor that uses an electronic module to control the spark timing and intensity. It is a popular choice for performance engines because of its reliability and ability to provide a strong spark.
Why do I need to disconnect the battery before wiring?
Disconnecting the battery before wiring is important to avoid any accidents or damage to your vehicle. A live wire can cause sparks or short circuits, which can be dangerous or cause damage to your vehicle’s electrical system.
What is the purpose of the stator wire?
The stator wire is responsible for producing the electrical energy that is sent back to the battery to recharge it. It is essential to the operation of the alternator and your vehicle’s electrical system.
What is the purpose of the ignition wire?
The ignition wire sends a signal to the ignition switch to tell the engine when to start and stop. Without it, your engine would not be able to start or run.
Now that you have all the information you need, you can confidently wire your 1-wire alternator with internal regulator and HEI distributor on your Chevy 350 from 1970. Always remember to take safety precautions and double-check your wiring before starting your vehicle.
