i have a SD35 premier proto 2.0 diesel. Had scale wheels ran great no problems just derailing. I changed wheels to high rail wheels from MTH. After that when I power up the the track that unit is on it trips right away. I can't see any pinched wires, any ideas of where to look? Thanks a bunch

Only the obvious, look at the trucks and the insulators for the center track pickups. If you disconnect the pickups from the circuit boards, you can see which truck has continuity from the wheels to the pickup.
Bryan,
Is this locomotive running 2-Rail? 3-Rail? What is the catalog #? Does it have a 2/3 Rail switch?

Hi guys, after removing the motor from the truck the red hot lead the attaches to the top of the truck had been compromised. Could not see it until removing the motor. That's the second MTH diesel that wires frade where the wires exit the body and go to the truck. Thanks for answering me as always. Diesel tracks so much better with hi rail wheels on three rail and adding traction tires it doubled its pulling power.
It's a very common place for issues. You can adjust the angle of the bend of the wire so it doesn't chaff on the slot. Also, I frequently cover that part with heatshrink to protect it against wearing the insulation through.

My 2 rail Gp's ..plenty of power but the wheels would spin on the tracks(towing 39 cars) so i just kept adding units. Middle of video GP's.
