94 pontiac grand prix 3.1. when driving in the day it seems fine, at night or when you put a load on the eletrical system the gauges go crazy, the lights go crazy and it runs like crap... alternator and batt are good all connections that I can check look ok the starter is new the egnition switch is new... complete tune up from top to bottom, when all this is happening the windows will not roll up either... somewhere in the eletrical but not sure what else to check... any ideas???
