If you plug the VR directly into the alternator harness IT WON'T WORK! You MUST run the blue field wire to D+. If the light doesn't come on with the key (engine off), then you will NOT have an operating charging system with the engine running.
Voltage at the battery terminals while the charging system is working should be closer to 14v, not 12.5v. If it's lower than 13v, then the charging system isn't working, and you're running straight off the battery, which is why you saw continually declining voltage. The VR AND the alternator AND the wiring all have to be good for the charging system to function. An inoperative charging system can be caused by ANY of those being wrong, not just the alternator. I agree with Rich, this is most likely a wiring problem, since that's what you've been messing with. The odds are good both the VR and the alternator are fine. |
