Big surprise, my truck is screwed up again. Well not really screwed up, just having a problem I cannot solve and it's driving me mad. Yesterday when I was driving, my battery light came on. Since in the past, this was always an alternator problem, I took off my alternator to see if anything was visibly wrong with it. There was. The cap that holds the bearing in was missing, and so were the bearings. So I went to get a new alternator.
As I always do because of duds, I had them test the new one before I left the store. It tested perfect. So I put it on, and put on a new serpentine belt, and the light is still on. Since the battery is less than a month old, I was certain that wasn't the issue, but hooked up the charger to it anyway. When I got in the truck after a while, It started right up, ran fine, but the stupid light was still on.
I also have a battery gauge on my dash that is supposed to be in the middle, but it's sitting about halfway between the middle and the low end. I drove it around for over an hour with headlights, A/C and radio on, hoping it would drain and point to a battery problem. The needle on the gauge didn't move a hair, and when I turned it off and waited a while and turned it back on, it still started right up, but the light is still on and the gauge shows the exact same reading.
Since I was at a loss, I figured what the hell, and took the battery to get tested. It tested perfect.
So WTF? The alternator tests perfect and is new. The battery is new and tests perfect as well, and the serpentine belt is new. The battery gauge reads low and the light stays on though, but the battery does not drain, the truck starts right up, and it drives normal. No blown fuses either. I'm at a total loss.
Any ideas?
