Hi, I would appreciate any help on a malfunctioning throttle on my komatsu pc130-5. The throttle does not work at all. The governor motor is not responding to movement of the throttle dial or the different settings on the monitor. There are no lights on the throttle controller behind the seat. There are two plugs going in to the governor motor. One a 4 pin plug and the other a three pin plug. There is only one 24v supply on one of pins in the 4 pin plug when the ignition is on. Should there be a second 24v supply on one of the other pins in the 4 pin plug? I would be grateful for any help. Kevin J.
