It is a traditional sized die cast dual motored GG1, green 5 stripe, cab #4930. Melted wiring and a stripped worm gear.
I replaced the burnt/melted wiring and got both motors to work. Is this thing one direction only? There are no switches. When I apply power or interrupt and then reapply power the motors only turn in one direction.
There are two circuit boards. One is for the horn. The other is wired for power/ground/lights/horn CB and motors. Quite a large board for one direction?
Can someone help with the truck worm gear? I dont know who to contact to order one.
Thanks for your help.
The circuit board that you say is wired for the power/ground/lights/and motors should have a few side by side places where about 3 or 4 four wire connectors look like they can go into is where the motors get wired into, not sure which as one of those slots can be wired for an extra set of motors.
You may have to order a motor to get the worm gear, be sure which motor unit you order it for, as there can be four motor possibilities. It might be best to order two motors so that they can be a matched set, otherwise one will turn faster then the other and one or both burn out.
My experience with a new motor upgrade kit was like that as I wanted to upgrade an F-7 A unit that had no motors, I got the upgrade and after installing it the new motored F-7 ran circles around my older F-7, so that is why I advise getting two motors that are matched.
