Hello all, my friend and I are trying to fix a switch problem on my Road Kings. We pulled the MPU board and found what possibly looks like add-on diodes to the backside of the board. The picture of the top side of the board is to show the corresponding area on the topside of the board.
Does anyone know if and why they would have been added and what their purpose is?
Quoted from themadman:Those are supposed to be there, the only difference from System 11 to System 11A boards was the additions of those 6 diodes. They need to be there for board protection from spikes back from the special solenoid inputs. Do not remove them... Someone modified the board correctly as the factory said to.
Ok, we won't take them off. Thanks for the info. Do you think someone added them and they weren't done at the factory?
