Well, it's doing it again.

Gauge shows high charge cycle....then goes to normal....then back to high charge. Tried the suggested running of a redundant ground from the alternator to th PCM. Didn't help I don't think.

When it does go to the high charge cycle, if I try to turn the volume up on the radio (using the steering wheel control), the volume goes down.

Also, during the high charge cycle, I'm seeing the instrument lights for the odometer and drive selector display flicker.

Had the alternator tested and it checked good, so is this all an electrical harness type problem or what?

Battery checked good....on the vehicle. Guy said it's either Alt or Regulator function of the PCM--system is over charging. So I'll check the alternator output and hope that is it.

Any tips on the alt testing. AutoZone guy gave me a print out on how to check for a "no charge condition"....figure I'll know the alt is faulty if I don't get a steady output or higher than 14??

Thanks guys.
