A WIERD electrical problem... HELP!

Hey everyone, I had a problem last night when I was driving home & I called Evan seeing if he would know anything about it, he coudn't figure it out, so I'm stumped...

Ok, my left headlight is dim, but my right one is fine, so I'm driving down the road & a little red battery light comes on & all my gauges ligh up really bright. Then my g.f picked out that my stock volt meter goes all the way up & my left headlight turns on. While the battery comes on my ABS light starts like flickering & stays on them it goes off. And my gauges go back to the normal "lightness" & my voltmeter goes back to it's normal position, & my left headligh goes back dim. And when the light is on & my volt meter is up, if I get on the gas it kind of goes up a little bit more. This happened like every 2-3 min. & sometimes it would stay on either for like 30 sec. or up to 5 min.

HELP!!! PLEASE!!!

Brenton

Poping fuses isn't something you can go by here. Those are based on amps, not volts. It sounds like your alternator is crapping a brick. I would cease operation and have it tested. If you keep going, you're quite likely to find replacing computer components and instruments a lot more expensive.

Remove the connectors going into your alternator (except the big lug on the heavy wire) and clean them.

If that doesn't do it, you may need an alternator -- but you also may have a major grounding problem as well.

Im with John here, it sounds like the voltage regulator in the generator is going out. That wouldnt explain the headlight issue though, that sounds more ground related.

Do you have any corrosion from the battery that got onto the ground wires?

here we go, go to auto zone and have em test ur alternator. i say alternator all the way, i have had wierd problems happen when alternators go out. could be the power regulator on the alternator, a little box on the outside. when this goes, all hell brakes lose, stuff gets over powered then underpowered, then the battery kicks in to compensate the brownout caused by the alternator, then the alternator comes back up and sense a draw on the battery to it pumps full 30 amps into the battery... first thing firt check all ur alternator connections and have it tested ASAP a problem like this may or may not "blow anything" but it could cause ALOT of head aches, especially in the form of stuff being 'half fried' whats that? thats when you start getting intermitten electrical problems in the vehical that cost time money agrevation. so, ya. there ya have it.
