GGG posted:The R2LC also controls Cruise board or motor driver. It is an easy swap to see if that resolves your issue. But while you are in there inspect the motor driver board for damage. Make sure all connector are attached, no wires off motor. Rotate motor flywheel to ensure you do not have binding of motor (tires off and stuck, linkage out of adjustment, brake detail stuck on driver, etc...) If binding it may cause your symptom. Other wise R2LC, Motor driver or a bad wire connector. Wire breaks under insulation at connector. Or else corrosion builds up so unseat 4 pin on motor driver and reseat. Tracking this down if no obvious damage to motor driver board is a lot more involved. G
I had originally check all of your other suggestions and as stated everything was nominal. However your suggestion regarding the 4 Pin is interesting. Is the board you are referencing in the Locomotive (Seems right). Is it the mother board that the R2LC plugs into? Assuming so since that board has numerous connectors for plugs, How do I identify the plug and pin you are referring to?
