i finally figured out what made my abs and brake light come on and my speedo not work....why my computer needs reflashed and why my stereo keeps shorting out. Warning to everyone. go to advanced or some place like that that does free alternator testing. My alternator was putting out 17-18V not 14 like it is supposed to. Aparantly it fried my engine pc...well started to which the dealer said that that is the reason for my spotty idle and random other problems along with what made my tranny pc foul up before i rebuilt it. after talking to the dealer mechanic though he said that this is a common problem with 98-02 and early model 03 1500 and 2500 gas engines. idk if this has happened to anyone else but i just wanted to warn as many people as possible to take some kind of preventitve measures to avoid a 2grand + problem.
