the Db king Posted March 8, 2008 Report Share Posted March 8, 2008 is it the denso (bird cage) alt on it or sone thing else, if it is make sure that you have all feeds to the 3 pin plug, there should be a ign feed, a battery feed, and the warning light feed, with a test light check that you have the 2 power feeds and the warning light with the key on will glow the test light dimmley and the light on the dash will be on just, if a bosch alt there will be a 2 pin plug on the back of the regulator, there slould be a battery feed and a warning light feed, (test the same wy as the denso) if thats all good then the prob is in the alternator itself.

kennc_87 Posted March 14, 2008 Report Share Posted March 14, 2008 check the charge rate on the alternator first to make sure it is the alternator circuit thats playing up and not the battery itself..brand new batteries can b faulty... grab a multimeter n check voltage straight across the battery terminals while the car is running..if its charging properly shuld b bout 13.3-14 volts..if not then it is the alternator n u can diagnose from there Quote Link to comment Share on other sites More sharing options...
