| I've found that, if you put a screw into the frame and running a wire off of it, rather than using the frame as the common ground usually fixes that. More direct current pickup....

Somebody soldered a green wire to the right hand motor lug and used one of the flywheel retaining screws to ground it to the frame. Originally there was a short length of bare wire that slipped between the motor and chassis for grounding.
Check the wipers on the insulated wheels. If the trucks are disassembled it's easy to let them slip out from behind the wheels.

That Zamac material can get heavily oxidized, I don't see it shiny in the picture in the motor cradle area, so it's probably NOT grounding very well thru the motor casing. If I was you, I'd buff it up some and make it shiny, and do the same on the motor casing. Or run a separate ground wire to the motor to ensure proper conductivity. Also, they zinc plate the steel (motor casing), it may not transmit electrically as well if the plating is hindering conductivity, might want to check it with a meter to see if you get a consistent reading of 0 ohms anywhere on the casing shell. Rough it up with sand paper to remove some, if you have to.

Hi Ken,
The wipers pick up from the insulated wheels with the plastic centers. The all metal ones conduct power to the frame through the axles.
Btw, do you have any spare parts for these Roco E units? I've been looking for a replacement idler gear. I need the smallest idler in the truck.
