The problem with external diodes as mentioned above is that the heat sink they
mount to will be at battery voltage. A better solution is to use a bridge
rectifier
so the diodes are insulated from the mounting package. Then the heat sink
will be electrically independent. Such a bridge is a Vishay 36MB120A ($8).
This is a 35 amp, 1200 volt device which is similar to the original Ducatti
diodes. I plan to install this Spring.
