I have a GN MTH FA ABA set, and have had troubles every once in a while. My train will stop and the lead A unit is scrabbling to move, the other powered trailing A unit has lost power. I have re-connected the plugs (harness?) and usually all is well. This happened again the other day, so I pulled off the B unit and hooked up the A units, and thins seem to be running fine, so far. Because of this, I am thinking I need to replace the male and female harnesses. MTH doesn't have a diagram for this FA, so what length do I need to order? Thanks!!
