I have an unresponsive O60 switch. It was wired wrong at the aux in and track power, so I swapped the wires. Still no response. I ordered and replaced the motor controller board to no joy. There appears to be a resistor in the shrink wrap in the picture. I get 14M ohms on that red wire, 2 AC volts with 18 applied. I was wondering if anyone can tell me the resistor rating and or the voltage that should be at the 4 pin connector powering the board,
so I don't have to pull another switch to compare. That wire with the shrink wrap goes directly from aux in to the 4 pin connector.
