could be the ecu also. the BSD line comes from the ecu and something is happening in the ecu thats tell the alternator to stop charging. i think i saw a post from one guy who disconnected the bsd line from the alternator and it didn't have issue with voltage freaking out. i didn't try it. but maybe it's worth a shot.
