My voltmeter normally sits about 3/4 in white region under all load conditions. However, in past few days it intermitantly goes up into the middle of the h red region on right side. At same time the interior and exterior lights are all significantly brighter! This will last for a few minutes whislt driving and then dips back to its normal 3/4 position.
Any idea what's happening?
