Headlights charge my battery; huh?

Ok, let's see who's run across this before. Vehicle: 07' Pontiac Grand Prix. Charging system voltage slowly drops while the engine is running. However, if the headlights are turned on the charging system returns to normal operation. Foot note; high beams come on sometimes when either blinkered is turned on....

Sounds like a grounding issue. I would check and clean every ground you can find.

Thanks aleekat. I had thought that originally with the high beams/turn signal issue, but really didn't think that would have such an affect on the charging. I'll check it out and let ya know how it goes.

Well aleekat, am guessing you already knew what the results would be; but, it worked. Thanks a bunch..... quick easy fix!

Good deal. Thanks for the update.
