One of this first things I did was put a new voltage regulator in it. I have power to everything however the battery does not charge. The motor is a 360 that has been built to a 408. Electronic ignition. No points. Automatic transmission. The only thing that I have added was a retrosound head unit radio. A replacement main dash speaker and 2 small kicker speakers under the dash on either side. For the power leg I tapped into the red leg going to the ignition so it will shut off when the car turns off. I have the same voltage at the battery and starter relay, had power going to the regulator when key in run position. I had roughly the same voltage at each lug of the ammeter. The alternator appeared to be putting out power. However with the engine running one thing I did notice was with the alternator the power was jumping all.over the place. One spot it'd read 13 then it'd drop to 3 for half a second then come back up. Only constant was power on the battery terminals because it wasn't charging just draining. I plan to do more diag when I get home later.
