A couple of my observations: Reverse contacts were dirty and I have cleaned them with an electrical contact cleaner The locomotive gets full power in reverse and the lights are on, but motor is dead The wires appear to be connected correctly and mostly from the factory I understand there is a neutral between forward and reverse Any help would be greatly appreciated Jeff

It has three wires: One goes to the right brush, the others to the reversing unit. Check the resistance between the right brush and the two other wires which are soldered to the reversing-unit. It should be a few ohm. Regards Markus

I am transitioning my father in laws collection and to get an idea of what I am working with look at the listings for "I want to sell" dated 9/24 under Marklin HO analog layout for sale. It is still for sale !
