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.
