Consisting Problem

<< < (5/5)

Alan:
Do you get same results without the freight car? i.e is the physical connection of locos relevant to the puzzle.

Swap LMs between the locos. Does the problem follow?

If not you might ask:
Certain all internal wiring is away from spinning parts of drivetrain?
No possibility of a swaying bare wire touching at a connector or in wire run?
Truck wires insulated and free of interference?
Foreign fragment of metal moving around? For instance a single strand of a clipped stranded hookup wire in the motor brush area.

I'm going to take a good look at all the wiring on that loco. The fact that the problem is intermittent leads me to think that is where the trouble lies. They do have to be physically connected, with or without a car in between, and they have to be facing opposite directions for the overload to occur. When facing the same direction, no problem. Pretty weird.

nodcc4me:
I believe I've found the problem. One of the motor wires was rubbing on a flywheel and a tiny spec of bare wire was evidently touching it. I insulated that spot and now they seem to be running together happily. I'll do some more testing to confirm. Alan, thanks so much for all your good advice.  :)

Alan:
My pleasure. Enjoyable, like reading a good who-done-it novel with the last chapter missing from the book.
