There's a Duraspark II ignition system in my 67 and I also replaced main front wire harness and all motor electrical wires. It has worked fine for 2 years but a couple weeks ago the car shut down while I was driving. I knew it was electrical and after a closer look I found some shoddy wiring and blown "Accessory" fuse under the dash from the knucklehead shop that did the wiring for me. They were running the ignition 12v off my radio lead and also spliced in a supply for electric choke on the same lead. I fixed the bare wires they left exposed and isolated the 12v ignition box supply to the stud behind the ignition switch and I'll plug the choke lead somewhere else. All engine & firewall grounds are good.
Now bare with me as I thought I had the problem solved but I actually found the real problem. I put a new fuse in the ACC (#1) location in the fuse box. I then turned the ignition to the On position and happened to have my hand behind the ign. switch to where the 3-4 wires come out from behind the switch. There are 2 large dia. wires back there, one is yellow and the other looks pink. The large pink wire was very hot which was probably the cause of blowing the acc fuse in the first place. I took the fuse out and turned the ignition back On and the pink lead is fine to the touch but of coarse I have no turn signals or back up light and radio supply until the issue is fixed and I can put the fuse back in.
The pink wire (from the ig. switch) disappears in the spider nest of wire behind the gauges and goes who knows where. Here's another clue, with the key "On" and the ACC fuse in (pink lead now getting hot), the voltage to the "I" terminal on the solenoid is only getting 5.5v. But when I take the Acc fuse out, the I terminal gets 12v.
Does anyone have any suggestions on what or where the problem might be? thanks in advance.
