Red and White battery indicator
Today I was at Sears auto care for a oil change and break check and asked them to check the battery. They checked the alternator and battery and it was all good. But while driving back from Sears to home (30 minute drive) the white battery light came up for few minutes.
What would cause battery lights to come up while driving and switch off automatically?




By the way we have two batteries in our GLs, so lots of connections to check.
