Marx Motor Problem

After running fine through Christmas, my Marx 10,005 engine has ceased to run. I pulled the motor, lubed it, cleaned contacts,commutator, and the e-unit. Buzzing comes from the e-unit. It is free and switching but wheels will not turn. Any suggestions.

Thanks - Ted

If you did all of that, and the wheels are not binding, the E unit probably needs service.

I replaced the brushes - looked OK but - It runs better than ever.

I think the title is a bit of an oxymoron, but I’m glad to hear you got it running
