Guys it is IMPORTANT to understand how the Mopar ignition circuits work. One big difference is that Ford, GM, and for some years AMC did the ballast bypass in the starter solenoid. Mopar never did.........they used the ignition switch
You have main power in............to the switch, hot at all times. NOTE that THIS IS NOT FUSED other than the fuse link which is nearly no protection at all
OUTPUTS are
1....IGN1 "ignition run." THIS IS ONLY powered in "run" and not in start, and is part of the trouble so to say
2....IGN2 brown/ bypass circuit. This is a separate contact and is only hot in "start" and runs to the ballast connected to the + side of the coil. THIS IS THE ONLY LIVE wire during "start" to operate the ignition
"1" and "2" above are what much be jumpered together if using ANY ignition system not using a ballast, or an EFI system.
3..."Start", usually yellow, this goes to the starter relay to crank the engine. "2" and "3" are both hot in start, but they are SEPARATE circuits. Trying to tie them together or substituting them will cause a circuit backfeed and other problems
4..."Accessory" powered both in "run" and "accessory" this obviously feeds accessories and ALSO drops off in the "start" position
