This alternator entire body model is exclusive to the Type 4 motor. Although the mount is analogous to other VW versions of your era (primarily watercooled) The truth that the motor is air cooled and demands a cooling port can make them unique.

Hardly ever underneath any situations get rid of the alternator while the battery is related so as to prevent harm to the voltage regulator. Never ever disconnect the alternator although the motor is working to prevent damage to the alternator.
I have a not really old bosch alternator and it has missing its demand? with my multimeter over the back again of it and immediate to damaging it nonetheless has nothing at all, this was a running driving auto and it just stopped charging??
