Alternator? Short? Bad Battery? I don't know. Odd coincidental events. Sign In

2001
Chevy S10 4 cylinder
110,000 miles.

The battery seems to be being drained rapidly.

Here is the sequence of events that led to this:

1) Everything seemed fine
2) Odd smells and steam were coming from under the hood, I deduced it was probably the radiator, and replaced it. That problem went away
3) The day after replacing the radiator, the battery light started coming on, then quickly stopped working entirely. It seemed like a huge coincidence but the battery is 5 years old so I figured I should just replace it.
4) I put a new battery in (tested), and the battery light stayed on and the voltage meter hung around 12.
5) I drove it sparingly for a few days. Then got the alternator tested at Checkers. The battery measured 200/445 CCA, the guy deduced the problem was the battery, not the alternator. I made him check the alternator anyway, it got 13.5v revved, and 13.1 idle. So it was bad, but not horribad.
6) THEN WHEN I DROVE IT from Checkers to get the alternator changed all of a sudden the battery light magically went away, and the voltage was hovering just below 14, FOR NO GOD DAMN REASON. I figured, what the hell? I guess it's working okay now. No problem starting up, and the voltage seems decently okay. So I just drove it home.
7) Two days later I was driving, the voltage meter started having an epileptic seizure, and my entire battery was drained to pretty much nothing in the span of about 20 minutes.

So I figured I must have done something when I changed the radiator, like caused a strange short somehow, but I do not understand this inconsistency. Can anyone explain it?
