malibu corevette alternator

[PBBWG]

I have a 1997 malibu corevette with the 383 stoker calloway engine and the volt meter is pegged to the right.

Any idea how many volts it should put out? Where can I get a new alternator and how much?

Thanks, Paul

Fairly sure it should be about 14 volts when the engine is running. Try resetting your laynard?

My alternator has an external voltage regulator mounted to the alternator. Maybe it's just your regulator.

Yes,...voltage should be in the range of 13.8 to 14.2 for a factory alternator. Jason I'm pretty sure his voltage regulator is internal and yours is too. You may have a high amp alternator with an external rectifier but anything as new as a 1990 should be wired for an internal regulator.

I am replying to the Alternator problem in question here. I took off the alternator, took to repair shop and yes it has a internal regulator. They said it was putting out correctly and went ahead and replaced the regulator in case it was intermitent problem.

I reinstalled the alternator and same problems.. Appears high output.. pegs volt meter on dash and engine cuts out.

Does anyone have a wire schematic or can you look at yours and help us trace wiring problems. We bought this boat recently and are having a hard time figuring out the problem.

Thanks

You may be dealing with a voltage sensing circuit issue. Many alternators are equipped with this circuit. It tells the voltage regulator what the system voltage is. In most cases this circuit is connected to the B+ side of the starter solenoid. If this circuit is somehow broken the voltage from the alternator will go to max which is about 16 - 18 volts. Check all wires connected to the alternator and follow where they go and check the other ends for secure connections.

I've also heard that voltage regulation of the alternator is a function of the ECM on some applications. Yours may be one of them. Just a thought.

I am trying to find a Corvette Malibu owner who can tell me how the electric Water pump is wired. Trace the wires/color ect.

Looking for the same information for the alternator. From testing we have performed we believe that the electric water pump is wired incorrectly causing the alternator to put out excesive voltage and shutting down the fuel pump.

We have also experienced burned out gauges, blower failure, and the electric water pump getting warm.

Any help here is appreciated.

Thanks much

Have you looked in any Corvette forums?

Within this site ? no, Do you have any links to any of them ?

Dennis, everything that is failing could be and probably is related to the over-charging alternator. I'd fix that first.

What makes you think the water pump is wired incorrectly? Has someone done some rewiring here?

i ve got a 97 vette,, i could shoot some pics of the water pump/wiring when i get back in town next tues if that would help you??

my alternator/gauge situation is opposite of yours, mines always reading 10.5/11 volts and keeps me worried about shutting off
