    I have a 99 Toyota Tacoma 2.4 liter. I jumped someone's battery a few nights ago. On the way home the truck started losing power. Lights on the dash dimming headlights dim when hitting the gas. wanted to shut off at the stop sign. Went to shift to third gear it wanted to shut off. Got home it cut off. Cranked up first try. Left it in neutral turned the headlights on revved the engine it wanted to shut off and the headlights and dash lights dimmed. Let off the gas lights came back up. I'm thinking alternator. Popped it off took it to autozone they said it was fine. They tested it twice. Brought it back home put it back in same problems. I still think alternator. Any advice or ideas?

    Update: had the battery tested it is good. Went ahead and replaced the alternator. Problem still exist.

    blacked out.
    Sounds more like wiring problem. all those light dimming and wanting to turn off are signs of bad battery or an alternator. have you installed any accessories on it lately? stereo or sound system or anything that have to do with battery? jumped someone's battery? i would assume you got a jump start? if you got jump start from another car i would recommend you to check for any blown fuses as well.

    i doubt the OP is still having the issue, but, how was the battery tested? even a battery with a dead cell will show 12.4v with a full charge.
