Coming home from the Hospital tonight I thought I noticed that my gauge lights were dimming. Like when the grid heaters are on, but I was doing 60 at the time and the volt meter didn't move.
I pulled off the highway (I figured doing 35 looking at the dash is better than doing 60. ) to look at them again and they did dim a little, the truck just kept running with NO signs of a battery problem or anything.
Has anyone had this problem?? I did a search and found nothing. Any help would be great...
