67 cuda wiring issues
Thanks guys for your help.
I will start with your suggestions today.
If I put my test light on the black with white tracer wire and turn ignition to the 'on' position, it lights up. The other wires don't.. That same wire also goes up to the fan switch. I'll see if I can get a couple of pics up.
Consult the diagrams or shop manual and look at the switch. There are only so many connections to the switch
This is from the instrument panel wiring, page 309 (8-122, 8-123) of the factory manual
Power into the switch is J1 coming up from the bottom an no 12 RED
START is S2, top left which is YELLOW
ACCESSSORY is just below it, Q2 which is a no 12 BLACK
That only leaves "ignition run" and the "bypass" circuit
=======================================
IGNITION RUN or IGN 1 is J2 DARK BLUE with TRACER and G5 on the right branches off to the right off the same terminal. G5 supplies power to the instrument cluster
THAT WIRE, the DARK BLUE is what feeds out through the bulkhead and powers the ballast resistor. This is one of the two you need for ignition. It appears out in the engine bay
THIS TERMINAL goes DEAD during START. Therefore you must also have the one below, the bypass circuit
=======================================
The last terminal is J3, at very top of the switch. It is BROWN and only goes one place---through the bulkhead, to the coil + side of the ballast resistor. It only has one job.....it is hot in "crank" and supplies "hot" ignition power for start. THIS WIRE and the dark blue / tracer "ignition run" must be jumpered together in order to "fire" your MSD
