OK..I have a new alternator,but recently the volt light will flicker when driving,stops when I let off the gas.
The volt light does not light up when I turn the key on before starting the car.
Should I check out volt light bulb and the contacts?
See if light comes on, if NOT...push in gauge cluster gently and if you see the light go on, take off your front plastic panel so you have access to the gauge cluster, and tighten the (4) screws around your gauge cluster. My bet is they are loose and the cluster is falling frontwards slightly
Ya, my experience with the inside volt readings is that they are a tad lower than at the battery/alt. My scanmaster is off about .3-.4 in my talon and I never checked on my GN.
I would bet that if you had a scanmaster you are pushing around 14.4 and is why the lights flickering.
I also have one of those volt regs that you plug into the lighter, pretty darn close also.
You might want to find a Bowling Green volt adjuster. It allows you to adjust the volts at idle and at WOT if you want by tapping into the TPS signal. It keeps your volts close to where ever you set it. I like it around 14.2 in my GN with the occasion light flickering due to the reason above.
Turns out the alternator was bad (or actually the voltage regulator)
Doesn't drop below 13.5 when revved up and the volt light no longer flickers nor the headlights
Alternator was 2 months old and the parts store warrantied it.
