Thank you to all that answered. I have tried all of the above. Alternator tests ok, new voltage regulator, battery tests ok, power to the fuse box on both side of each fuse, cleaned the bulkhead connections...still goes to discharge upon starting. Anyone have any other ideas? I never grew up wanting to be an electrician...possibly a high voltage ground, or the gauge itself? Where would you guys start looking? Any other ideas would be great!
