My volt meter drops from 14 to 12 when I turn on headlights.Alternator checked out fine. Any ideas.

Where's the meter tied to?..The IGN terminal on the fuseblock? Does it do the same thing on the BAT terminal on the fuseblock? Don't leave it connected to BAT. It's just a question. Leaving it tied to BAT for a long time will run down the battery.

Thanks, I will check tonight. I believe the guage is wired ok since it was done 6 months ago.

Mine does this too, i never thought it to be a problem, but maybe check the water in your battery? Might be low. I just figured that the headlights would cause that much of a drain on the car when you flick them on. My guage also moves when my headlights are on and i am using my blinkers.
