My 03 2v OEM alternator is on it's way out. has 31k on it but is 14yr old. was having noise coming thru the speakers. I unplugged the alternator and the noise stopped so i know it that was the source of the whirling noise coming thru the speakers. Does that mean the diodes took a crap? 20yrs ago i rebuilt an alternator in auto electronic class, but i don' remember too much from it. Where can i find a rebuild kit and which pieces should be replaced? Can i up the amps?
