Changed the wiring back to Bob's recommended configuration eliminating the stator connection on the alternator, removing the "I" spade from the VR, and jumpering the A and S spades on the VR. The pink wire is still disconnected from the fuel sender. The charging works again, but of course no tach or anything else on the ignition circuit.
And with all that disconnected, if you put a fuse in #3 it still blows?

Default Ideal circuit Tracer

If you would like, I would let you borrow my tester, it is a very high quality unit I paid over 900$ for. You may use it as long as you would like. Met you at the restaurant a year or so ago and you took me for a ride in your superformance. There are instructions in the case and you will need AA and 9v batteries Hope this helps you.

John,
Thanks again. Responded to your PM. I'm curious what kind of tester it is and how it works.

That Ideal tester looks very cool. Not sure it's small enough to troubleshoot my car wiring loom, though?

Fortunately, Fuse #3 does not carry much amperage at all. I know you don't want to but, starting at the far end of the circuit, and then snipping the wire, in stages, until you can run what's left of the circuit without the fuse blowing, and then slowly butt-crimping the wire back until the short re-appears, works every single time, especially with funky intermittent faults that seem to come and go. With wipers running, the heater fan on, and all gauges working, I bet that circuit doesn't pull but five amps. For something like that, a butt-crimped line will work just as well as a brand new wire, and no one will know the difference. (It's what I would do, and then heat-shrink the butt-crimps and they'll look OEM, not that anyone will every be looking at them.)

Evan,

I'm hoping the cause is in between the voltage regulator and the ignition warning light. What I will do is give you a replacement for everything in that circuit, from regulator to light to power. The leads will be long enough to test before a permanent install parallel to the original leads.

Thanks Bob and John! Need to focus on getting the car ready for Cobra Day, but hope to get back to troubleshooting Sunday.
