Quote: I am using the stock wiring harness except that at the bulkhead, I had to bypass the blue wire around the bulkhead last year due to a burnt connector. Since the bypass, it ran fine all last year. This came up on my last thread so I will throw it out there. I just installed a MSD ignition box and on the 12v switched feed to the MSD box, I connected three wires, the RUN blue wire (goes to the alternator/VR), the brown CRANK wire, and I also wired in the voltage guage that is showing a fluctuation of 13.5-14.5. These three wires are what is feeding the MSD 12v feed. I asked a MSD tech about wiring the voltage gauge in on the 12v supply and they said that it would be fine. I am not 100% sure on this as other board members have questioned it too.
Thank you.
You answered your question here. You had to by-pass a burned connection. You fixed one, you probably have atleast one more.
I had the same problem on a 71 Challenger R/T. The ammeter gauge would discharge a little at idle, not much, but when I'd rev the engine or drive, the needle would go way up. I changed voltage regulaters, alternators, added grounds, did who knows what all. Still no solution. I actually cooked the battery one or two times. Litterally blew the caps off of it. Had it to a few shops and no one could find it.
One day I was messing around looking under the dash and noticed a black streak in the steering column to main harness connection. I tried to pull it apart, but couldn't. So I cut the wires and spliced the two together. From that point on, the car charged correctly.
