Question about 1993 Jeep Grand Cherokee
Hello! There are 4 wires in the alternator connector...Red...Dark Green/Black...Black...and Dark Green...It looks like torque plus vibration is causing The Red ( or Red/Black...Colors change from 60A fuse to alternator) wire is to close to Black...Take a close look at the connections on the alternator...And make sure that the hot lead isn't close to ground...It's carrying a lot of current and will find a path to ground if one is available...You can view the area when it's dark and see if you can spot current jumping...You will have to simulate vibration...
Let me know what you find.............Guru..........Saailer
