Having some issues with the electrical systems in my 2002 P5 alternator tests fine but it keeps blowing headlamps and cooking the battery any ideas would be greatly appreciated
 
How was the alternator tested, hooked up in the car or off the car? I would take it off the car to be tested. An just my opinion, don't but cheap rebuilt ones from the AutoZone or O'riely.....Also check all the wires to make sure they are good and not touching anything. All your grounds in place and not loose, hot wire connections are all tight....stuff like that.
 
I tested it in the car with a midtronics tester and then verified it on the alternator with my multimeter and then I ohmed all the major grounds not testing where it connects but scratching paint and testing what it is connected to I think I'm just going to try the Big 3 mod and see what it does
