Flyby736 Posted February 7, 2004 Report Share Posted February 7, 2004 The voltage that my car reads seems to be different everytime I start the car. Sometimes it reads really high and sometimes its down around 14 or so. When it reads high the car seems like it has a lot more engine power than when it is reading low. Also the voltage bobs up and down when the turn signals are on. Is my alternator going out? Its been like this for a while, seems like it would have ate it by now...

digitaloutsider Posted February 8, 2004 Report Share Posted February 8, 2004 Seems like your everyday W-body anomaly. I've gotten used to it. It can also do this if your battery just needs more of a charge. My GP does this off and on. Nothing serious. Quote Link to comment Share on other sites More sharing options...
grandprix104 Posted February 8, 2004 Report Share Posted February 8, 2004 if the voltage is fluctuating quite a bit I'd take it down to Checker/Shucks/Kragen or advance and have them test it. The regulator *MIGHT* be going out. If its putting out over or around 14 volts you should be just fine though. Quote Link to comment Share on other sites More sharing options...
Flyby736 Posted February 8, 2004 Author Report Share Posted February 8, 2004 I dont suppose its possible to change the regulator without changing the alternator? It does stay over 14, thats usually the low, but other times its up around 18. It just seems kinda wierd that it bounces with the turn signal and the car feels slugish when its lower too.

joey b Posted February 8, 2004 Report Share Posted February 8, 2004 you CAN buy a new regulator. You will have to remove the casing to the alternator and solder the new one in. But they can be bought for like 12 bucks. Quote Link to comment Share on other sites More sharing options...
musthavemuzk Posted February 8, 2004 Report Share Posted February 8, 2004 or you can find a shop locally that rebuilds alts. and have it all gone through for cheap. 50-100 but yeah take it to autozone or another place and have them test it. some will do it on the vehicle some will have to have it off the vehicle. but they can tell you if it is good or bad or weak.

I think the 36 mo warranty at checker is $94 and the lifetime (very good alts) are around $120. Quote Link to comment Share on other sites More sharing options...
Thabulldog Posted February 9, 2004 Report Share Posted February 9, 2004 Check the battery cables too, just a thought. Mine was really really loose until the point the car died when I hit a bump. When it was loose the lights would flicker when I hit the brakes and the dome would dim out when the hazards were on. Once I tightened it, everything stopped.

navyguy2010 Posted February 21, 2004 Report Share Posted February 21, 2004 My 90 GP does the same thing, but everyonce in a while it spikes really hard and shuts stuff down. Just the other night, it blew all four, Yes I said ALL FOUR, headlights!!! I took it to a mechanic to check it out, he said everything checks out alright. I dunno what the problem could be. Any help would be greatly appreciated. Quote Link to comment Share on other sites More sharing options...

Turns out my alternator went bad, got me stuck on the trip home from PA this weekend. 70 bucks later on Monday it was done in 10 minutes.
