so i put a new battery in my car about 2 months ago and ive already had to jump it because it was dead. at first i thought the alternator may be going bad and not charging the battery enough, so i took it to autozone to get it tested and its all good. then i was thinking, could the voltage regulator be doing it? could it be dropping voltage off?

 

anyone????

 

Dude, it's probably not the voltage regulator. It might be but you should check the sensing wire first to save yourself the trouble, and the guys at autozone aren't that smart so you hsould test it yourself. And make sure that you don't have a short to ground anywhere bro....anything else just e-mail me, I know what I'm doing damnit...lol

 

dude im having the same ******* problem.

something is eating my battery power..............

someone plzzzzz help

 

Why can't you get a DMM (HINT, Sears has it on sale for HALF PRICE FOR $10 now) and troubleshoot it yourself?
With the DMM, you can check the voltage - this will eliminate the voltage regulator.
With the DMM, you can check current draw - which is most likely - and track down whatever is sucking up current with the key off.

Voltage regulator is built into the alternator.

 

the alternator has three transitors that create the feild winding, to generate the power. one can go bad or two, and still have the alternator produce power, but at less amperage.

just do some tests, start the car and check the voltage going to the battery, it should be close to 13.5 - 14 volts. also put some load on the batery when your doing this, headlights, rear window defroster, ect.

my alternator went bad the other day for no reason, i got one at the junkyard for $20.
