I've been fighting an electrical gremlin for a while now. Just got the car to maintain a somewhat consistent charge of 14.1 to 14.5v. All of the lights are still fluctuating and I can't figure out why. The VR has been replaced with a VR706. That helped the over charging I was having. The alternator is a reman square back style. I've grounded one of the brushed back to the case. Today I was checking voltage at the alt terminal and it was consistent with the battery reading. However, and I don't know what made me so this, I touched the alternator case with the probe a got a voltage reading. Not a consistent one, it was all over the place, but still voltage. I tried grounding the second field directly to the negative side of the battery. Same thing, voltage on the case. When the car is off there is no reading. What should I look for inside the alternator to cause this? Could this be a cause of the fluctuating lights?
