voltage regulator

Does anyone know where the voltage regulator is located. I think it is either in the alternator or the computer. Also how would i be able to tell if it is going bad. Right now my volts get very low when i use light radio ect

I THINK (but don't quote me on this) that the voltage regulator is on the alternator itself. At least, this is how I've seen it in other cars, but honestly I don't know about the XJ. You can go to Autozone and they will test your alternator for free. It is also possible that your battery is not holding a charge well, putting extra strain on the alternator.

Sorry for not being sure on that regulator location, but I hope this helps.

Good Luck,

Peter

The voltage regulator should be in the alternator. At least that what Autozone just told me,...

I would try another alternator, I have seen people by new (rebuilt) alternators only to find out they were bad... Also you can take it to Autozone and have them test it for free like Islandroaddie96 mentioned.

Before you go round and round, check all of the grounds, and their connections.If the alt is good, more than likely thats the problem
