Ok so I looked at the car this week and havent checked the main fuse to the alternator! But at night when we are running a load (lights, fog lights, stereo, and heat) or even if it is just one of the two the car lights dim and the tach goes to 0 rpm's! I will be checking the fuse on saturday, just trying to figure out if im in need of a new alternator or not, if so this will be the 5th or 6th alternator from 56k to 120k? Not sure why but oh well.

Any help is appreciated thanks.
