This a.m. I noticed my volt meter was PEGGED. When I came to a stop, at an idle, it went down to about 14 volts. When I accelerated - it PEGGED again!!!
I thinkin' voltage regulator - YOU??? Thanks, Gary |

put a meter DIRECTLY on the battery posts and measure.
sounds like a bad VR to me but i have no confidence in the console meter... don't run it long like that, too-high charging voltage will kill a battery in a hurry |

When mine did that, initially I replaced the VR, but that didn't do it. I had to replace the alternator. Really surprised me....

Hijack....
DO more modern cars have the regulator built into the alternator? The subaru alternator seems to be piped (and I mean piped - 100amp fuse) directly to the battery! Fiid. |

The points in your mechanical voltage regulator are stuck. Very bad! Get a replacement solidstate regulator (I got mine at NAPA). Your regulation will be better and your battery will last longer. Your regulator is on the relay board in the engine compartment.
I know from experience with the same problem. I quick rap on the regulator broke the points loose and gave me the time to get the replacement. Kit |

Done deal (IMG:style_emoticons/default/smilie_pokal.gif)
Replaced the voltage regulator, alternator, belt, battery and ground cable. All's well - Thanks, I'm happy that fixed it. I had a car many years ago that fried the wiring harness when I shut off the engine. Damn vr stuck in the "closed" position. That was not a fun fix. Gary |
