Having some electrical issues in my 67 gs. 455/th400. Never really had any electrical issues in the past. I put in a blue sea systems fuse panel to add some accessories while still running the stock one. Added a stereo and 4 speakers while doing that. I routed my tach, along with other gauges, and my kick down to the blue sea panel as well after. Was firing and driving without any issues. I noticed initially my turn signals went, replaced the flasher. No change. My tach started to show innacuracies, as well my voltmeter was reading in the 16-17 range. While almost being home, the car quit while going about 55. Would crank without issue, just won't fire. Waited a couple hours for everything to cool, fired up and made it about another mile, then same thing. Replaced ignition module as I had a spare, no change. Tested coil and shows in working condition. Took the top assembly from my spare 455 hei and placed it on this distributor. Same thing, no change. Using a stock 10si Alternator with internal regulator. Was told it could be my regulator. Whats the advice from the pros here?
