Re: Ignition wiring question on a 66
In an attempt to clarify-try and disregard the prvious post when reading the following:
The fabric coated wire is a resistor wire which reduces voltage to the coil from 12v to 9v and is the primary positive feed to the coil when the engine is running (key switch in the "ON" position).
The purple wire is routed to the starter solenoid which activates the starter when the key switch is in the "START" position. During this event, the solenoid acts as a relay to route 12v to the coil via the brown wire for starting events only.
YES, you need it connected if the remainder of the coil/solenoid connections are installed correctly. I suspect that they are not since your engine continues to run with key switch in the "ON" position...Meaning you are sending 12v to the coil at all times.
