I had a problem with the black wire that comes out of the alternator plug on the side of the alternator (the "field" wire, idiot light wire as some call it). The wire no longer will run the alternator. According to the wiring diagram, it goes in the dash to the battery light. I guess it's burnt out, but that's a pain to change.

But here's the thing... I don't have any of the stock motor left in the car, it's HEI carb'd with vacuum advance. So I direct wired the alternator field coil power (the "black wire in the plug") temporarily, and make sure to unplug it when I turn off the car. It's been working for a week.

Today, I decided to find a source of ignition power under the hood, which I got from the harness. Problem is now, the car stays running even when I turn the ignition off! I imagine it has something to do with the fact there's no resistance in the wire. Can anyone suggest a solution to the problem, ie. a resistor value to put on it, or maybe could wiring a dummy light in-line be the solution?

 

Pick a different keyed source. The alternator is keeping it energized with 12v and won't turn it off
