Diode Pack/Rectifier bridge for Dodge Diesel Denso alternator
Rarely does the diode pack fail unless while jumping the battery with jumper cables someone accidentally crossed the cables. (not you of course :)) or allowed the cables to touch each other or ground while the motor is running. This will toast the diode bridge. These things are costly but still less than buying a new alternator. For Denso alternator only. If the two small wires on the back of the alternator attach to two seperate posts then you have a Denso. If they attach with a rubber plug then you have a Bosch. This does not fit the Bosch Alternator!!!
