Max Voltage!

Ok, I have used the search feature on the forums, and I say I think I might have the standard answer, but I would like to get an individualized, personal answer.

This just started today, which pisses me off because I bought this car 2 weeks ago and it didn't do it before today.

I have a '94 camaro 3.4. When I cut the car on the voltage pegs to 17 or 18 then drops, then back up, then drops, and sometimes stays at 17 and the headlights get really bright for a minute or so, then drops back to about 13 or 14. After I have been driving for awhile (about 5 or 6 miles) it stabilizes at about 13 or 14. Then the service engine soon light comes on, then after about a minute it will go off and everything is fine. What exactly is the deal? The engine light might be totally different, because I actually did notice that the second day that I drove it, but it only stayed on for a minute tops. Also, the when idling the temp gauge starts creeping up higher and higher (it normally sits a little below the middle mark). It hasn't overheated or anything, but I smell the infamous smell every time I cut it off.

Am I going to blow up something besides the battery if I continue to drive it like this? I really need the car for transportation to work, so I would really like an answer to this question as well. I am a young guy that has 0 experience in messing with stuff in cars. What route would I go about doing what you suggest? Please help me, the idle gauge creeping I can deal with. Pegging out on the volts is something I cannot.

Re: Max Voltage!

The overvoltage, reason why the SES light comes on, is, I would think, a result of a bad regulator inside the alternator, or a poor sensing connection.

A free alternator check out at Advance could help diagnose. Get it fixed soon cause you'll be replacing bulbs and other electrical items soon.

Buyer beware of used cars.

Re: Max Voltage!

How would I go about fixing that? Also, about how much does that cost? Please reply, I live in BFE and do not want to take it to the ford dealership that is just going to hook it up to a computer and charge me $75 to hook it to a computer for something that could be done for less than that.

Re: Max Voltage!

I answered your PM. Don't you have an Advance Auto store?

Re: Max Voltage!

The alternator voltage will also shoot up if it becomes disconnected from the battery. Check the battery terminals, all of the large wire from the alternator to the battery, and the ground cable between the battery and engine.
