Had a bunch of switches go out on my Road Kings. Come to find out, it is the entire column 4 on the switch matrix. J8-4 has continuity back to the board. All the J10 wires have good continuity also. Pulled J8 and J10 and tested with a jumper and every switch is dead. Leads me to believe it is the transistor at Q48?
