    Have a look at the battery under the rear seat, see if the cable to that bat is loose any. (I'd be suprised, but you never know.)

    my battery is under the hood, that was the first thing i looked at, could a bad alternater cause it?, but then it starts right back up, it has me baffled.

    Unfortunately, I'm no electrical systems specialist. My other uneducated guess from other posts would be a relay. We'll have to wait for a more experienced reply.

    But someone here had a different problem where the alt fan would come on with a couple of faint dash lights coming on when the engine was off, key out, and it turned out to be a relay problem.

    Mind you, with a Toyota I used to own, I blew the alternator, and so all the electrical had gone. I jumped started it a couple of times (push, 2nd gear... that routine) and took it to a garage.

    Perhaps a look at the Bentley manual might help. You can download it. Somewhere within the threads here is a link to a 60MB file in pdf.

    Ah, here we go, fusible link. I do like to type for no good reasons sometimes.
