Key on wire for MSD ignition and one wire alt
Thanks Joe. The first (top) part of Joe's photo is how "many" years are wired. There are a few years where some of the colors are different
The big red is main power coming "into" the ignition switch, is hot at all times.
The big black is "accessory" power going out, hot in "run" or accessory
Dark blue is ignition run, hot ONLY in "run" but dead in "start" THIS IS THE ROOT OF THE PROBLEM..........this wire goes dead in start
Yellow is your "start" wire fires the start relay. DO NOT USE for any other purpose
Brown is the wire in question. It is hot ONLY in start but comes off a SEPARATE contact in the switch, that is "a separate switch" within the "can" that "is" the ignition switch. This wire only goes one place.........to the coil + side of the ballast relay.
