Morris Minor Owners Club

Looking at the imprints on the washers, the stud on the right should be insulated as the one at the top as they carry current and the stud at the left does not need a washer as it the fixing point for the heatsink to the back cover. Think this correct - unless someone knows differently.

Busy rebuilding my alternator and cannot remember where the insulating washers went on the 3 studs on the diode heat sink. Not sure if this is right or if I have lost a washer.
