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.

I’m interested in the tester if it will help find a short. Are you coming to Cobra Day? Evan |
Sent you a p.m. Yes the tester is a high quality tester just read all the instructions Play with it all you want keep it as long as you need.
|
John,
Thanks again. Responded to your PM. I'm curious what kind of tester it is and how it works. Evan |
NO thanks needed, you are a good man. I emailed you some pictures . I have not forgotten my promise about breakfast so I will make it up to you and bring you the tester.
|
That Ideal tester looks very cool. Not sure it's small enough to troubleshoot my car wiring loom, though?

Dropped off the tester today .Hope it is useful . IT has many functions and comes with a amp meter It is a Ideal suretrace open/closed circuit tracer #61-957

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

I'm finally getting back to troubleshooting.
I ordered one of these: https://www.realfixesrealfast.com/short-finder.html Basically an automatically resetting 10A circuit breaker with a Gauss meter to detect current. I clipped the CB to a test light to have a visual indication of the breaker tripping and replaced fuse three with the set up. I reconnected the stator and VR to the circuit, but left the pink wire from the dash to the fuel sender disconnected. When I turned the key to ACC, the test light lit, but the ignition light did not. Also, the CB did not trip, suggesting it's either way more than 10A (15A fuses blow in fuse 3), or faulty. I turned the key to "on", and again no ignition light and no CB trip. I started the car. The ammeter was charging, but no tach. The test light remained lit, although it seemed a bit dimmer than when the key was in the on or acc position. I reconnected the pink wire to the fuel sender and no change--no acc or on ignition light, car started fine, and ammeter worked. I disconnected the pink wire again. I inserted a 10 Ohm shunt resistor in parallel with the ignition bulb Bob sent me. The purpose, according to Bob, is to add current to the VR energizer circuit guaranteeing actuation. I removed the CB from fuse 3 and repeated Patrick's test with the auto-reset CB + test light jumper between the ACC terminal and the outer (double green wire) tab on the ignition light. Both the ignition light and test light lit (although dimly). I put everything back together, put a fuse in #3, turned the key to acc, and the ignition light illuminated. Turning the key to "on" and the ignition light still lit. Starting the engine, the tach worked, the gas gauge moved off E, the ignition light was not on. Everything seemed to be working correctly. I reconnected the pink wire to the fuel sender and the 15A fuse 3 blew. I disconnected the pink wire, replaced the fuse with the CB and test light. No ignition light, no tach. Started the engine, the CB did not trip, the tach didn't move, the ammeter showed discharging, but not charging. I'm now thinking I have two issues: 1) a ground loop or short in the pink wire to the fuel sender, and 2) an intermittent VR. Thoughts? |
Thoughts - man, you have a lot of patience and perseverance Evan. I'm no help but hope you get it figured out before long.

Dan,
Thanks. I've basically taken a 3 month hiatus. Just now getting back to it. The fact that it almost kinda works makes me think I'm definitely gaining on it. As the joke about the optimistic kid goes, "there's got to be a REALLY COOL PONY under a pile of poo this big!!!" |

Why do you say that? I could understand if the lamp was in parallel with the breaker, but in series amps is amps. What am I missing? Evan |
I didn't have any of your other symptoms, but I recently discovered that the white and pink wires were reversed at the fuel sender in #3014. Since my car has SW gauges and no requirement for the pink hot wire, this means:
1. fuel gauge was inop because the white sender wire was no-connect at the sender; and 2. the 30-240 ohm fuel-level rheostat in the tank was functioning as a 0.6-5 watt heater because it had +12V applied to it via the pink wire. Bill |
