I searched the forum for the questions I'm about to ask, but didn't find anything. So, if these issues have been discussed before, please excuse the duplication.
Two issues I'm having. "Issue One", as John McLaughlin would say, is I am having problems with an Atlas HO Dash 8-32BWH. It's the phase V Amtrak unit, AMTK 517 and, for the life of me, I can't figure out why the thing binds up and, ultimately, shorts. I've checked the trucks, and there's no binding there. I've checked the flywheels and motor shafts for binding, but found none. I've shimmed the motor up a bit, to adjust the angle of attack for the front driveline. (It's the front that binds up.) I've checked the gauge on all the wheels, and the gauge checks out. I've played around with the worm gear female receivers, thus shortening and/or lengthening the drive, to no avail. I had the unit in at Atlas awhile back, and asked about binding in the drive, but they must not have found anything. I can't figure this out, and it's about to drive me up the wall. I have not yet tried changing the PC board, but it doesn't seem like that would be the problem. What do I do with this thing? I have the other two units from that release, and they had some binding issues, as well. I was able to resolve it by tinkering with those worm assemblies and female receivers, and they seem to be doing OK.
My other problem unit is a Kato HO Amtrak F40PH (AMTK 400) that likes to stall. It'll be running fine, and then... out of the blue... it just quits. Stalls completely. There's nothing wrong with the motor that I can see. I've adjusted the copper clips that connect the contact bars to the PC board, so there's no slippage. Yet, the unit still stalls. I have the other two sister units, and they don't seem to have that problem.
Suggestions?

I thought the F40s were supposed to be the good engines!
