Pilot or trailing truck isolation

[twilight]

Ray, originally these locomotives came with metal flanged disks with a plastic core molded together to represent the lead truck/wheel and trailing truck and I also believe it pertained to when the locomotive kit was made. Bowser, I have found tried to make improvement with thier kits along years they produced them. When I had first assembled them locomotives(last year) some of them had come with the metal/plastic wheels, I have converted them over to all plastic aside from the axle and the locomotives ran without interuption ie: shorting for over an hour. Enough time to feel I had eliminated the shorting problem at that time. My plan is to take them up to the club this weekend and narrow down the problem as I had done before. Run them with both trucks, run them w/o the pilot, run them w/o the trailing truck. If they are still shorting then the problem may likely be in the running gear, like you had mentioned.
