Sunday, I had my hood opened and cranked my 01 Taco and a little smoke came from the negative terminal. I thought, either it was dirty or there was a short, so I cleaned the terminal and the smoke problem was solved.
Monday and Tuesday, it cranked and drove normally.
This morning, as soon as I put the key in the ignition, the door-open bell was dinging and would cut off, ding a again, skip a ding, cut off, etc; it was definitely struggling. The interior light wouldn't come on (I keep it in the 'off' position at all times, so I didn't leave it on and drain the battery). I turned the ignition and I could hear the starter click, but nothing else.
I didn't have time to jump it off, so I just got in the fiance's car and went to work. At lunch, I'm gonna take a multimeter to it to be sure. The battery is just an el cheapo AutoCraft from Advanced Auto Parts from probably 2 years ago.
I'm just wanting to verify that this sounds like a classic case of a shot battery.
