Diode board
Diode plate 14V 22AH for 2 valve Boxer. The original for a good price.

This is one of those parts that can and eventually will fail on most 2V boxers. When it does, your charging system stops working and the battery is next. On a long trip, it's always a good idea to have one along.

Price per piece.
