    Alternator replacement diodes for SEV Marchal

    Hi all, I’ve just pulled out the alternator assembly on my 71 911E 2.4, the batteries have not been charging and the charge light has been on since I bought the car. The Voltage Regulator has been tested as swapped and is not the problem and all earth straps look to be fine.

    Being a low milage car I figured that the alternator, might have a simple problem rather that needing a full rebuild as one would expect on a higher milage vehicle.

    I’ve checked the carbon brushes and that are in good condition almost 1cm in length, then I spotted a broken wire on the back of one of the diodes (See top left of photo).

    Does anybody have recommendations on how to correctly remove the diode and secondly where to get a replacement?

    Thanks Andrew
