First I assume you mean that the volt gage is reading in the red portion of the scale. The problem is that the voltage regulator is not working anymore. Now how to fix this problem depends on what year yours is. But first check the voltage across the battery using a test meter it should be between 12.5 and 14 volts, remember to test while the engine is running around 2500 rpm because at idle you can still get normal reading even if the regulator is bad. If your readings are like 15 or more then it's the regulator.

If it's an 80 or 81 it has an external voltage regulator and you just need to replace it.

If you have an 83 it has an internal voltage regulator that's inside the alternator. I belive you can open up the alternator and replace the regulator but most people simply go and get a rebuilt alternator from a parts store or they find a good used one.

For 82, I can't remember if it had an internal or external regulator.

Craig is right on the money. Do it soon since the overvoltage can harm other electronics in the car--some expensive (ECU) and some not so expensive (headlights).

another check mark beside Craigs answer
and you better believe what Ed says
it can also cook your battery in short (operative word) order.

I have changed internal VR's, it takes heat sinks and a good solder touch. I swapped them from alts with other problems (blown main diodes)
I like Craig's idea of getting a rebuilt or just another alt from a bone yard.

If it helps I think the voltage regulator on my brat is in the alternator as it takes the exact same alt as my 87 GL

For some reason though, my voltmeter runs at 12 volts ALL the time even though the autozone diagnostic machine showed 13.6 or something... <img src=http://www.ezboard.com/intl/aenglish/images/emoticons/ohwell.gif ALT=":\">

The gas guage is sometimes kinda slow to "wake up" when the brat has sat afew days too (takes like 5 blocks)

Maybe its time to yank the cluster and clean it up.

82 uses an internally regulated alternator, my 82 sedan's got one in it. I'd get that shiznit replaced before you cook your battery, you might want to have it checked too (overcharging will boil the water out of it)
