Had a weird voltage problem today in my truck... Just driving along and the radio volume cut down like I had turned it down myself. Then the whole truck started tripping out, chugging along... I barely made it to a parking lot and it was zapped. When I turned the key, I got the clicking like it was the starter, but then got a jump and it started fine.
Then I had another jump from roadside assistance and the battery is whacked. It's 6 years old, so it wouldn't be out of the realm of possibilities that it needs replacing. I managed to limp it to Walmart and bought a Jumper box, hoping I could make it to an auto parts store to buy an alternator. The truck said no, so I had to get it towed home.
I charged the battery on a slow 2A trickle for a couple of hours and it started up right away. If it's dead tomorrow, all I can think of is the battery is completely whacked or the alternator is, but I have never had an alternator die while driving, never even heard of that. It was fine for the hour or so before that, then the alternator dies and coincidentally, the battery has no juice at all? Never had that happen.
