I have just put the drive gear and the springs and brushes back on the pancake motor of my tyco Rock Island Line Loco made in Hong Kong. I had to disconnect some of the wires going to the motor and now I don't recall exactly where they go. I don't want to take the chance of burning up the motor as I have put too much time and effort in getting this far. Can someone provide me with a wiring diagram (I don't care if it is hand drawn) as to where the wires go. I have attached a photo of the motor.

First test the motor one wire to a brush from the transformer (DC)

Then One wire from a brush to a truck but the truck must be isolated from one side for it to work and each truck uses a different rail.

Motor testing and wiring

I have just put the drive gear and the springs and brushes back on the pancake motor of my tyco Rock Island Line Loco made in Hong Kong. I had to disconnect some of the wires going to the motor and now I don't recall exactly where they go. I don't want to take the chance of burning up the motor as I have put too much time and effort in getting this far.

HOFAN;

Reassemble the motor & entire power truck, but don't install it in the loco yet. Then put a 9 volt battery's contacts on the two copper brush plates on the outside of the motor. (You can't hurt a 12 volt motor with 9 volts) The motor, and all the gears & wheels, should run. Next,turn the battery around and try again.The motor should run backwards. Now that you know you have fixed the motor, re-install the power truck in the locomotive frame. Connect one of the motor's wires to the wire from the wheel pickups on the front (non-driven) truck. Connect the other motor wire to the other frame wire. It doesn't matter which motor wire you use, for now. You won't hurt the motor. When both motor wires are connected to both engine wires, try running the loco on the track. It should run. If the loco runs in the opposite direction from other locomotives, reverse which motor wire is connected to which wire from the engine/frame assembly. This will reverse the direction of travel, so that it matches the other locomotive(s) on your railroad.

Good job!

Hint, next time mark the wires, and/or take a photo of the wires, before you cut them. ;)

Wiring Diagram

Thanks guys. Using your directions I have the wires in place and the motor is running. All I have left to do is put the truck assembly back into the shell, which I will do shortly. In case you didn't see it, I posted a slick way to put brushes and springs back into pancake motors. It's so simple and once you pull the slack out of the loop you can take your fingers off the brush as it will stay put until you cut the ribbon and pull it out of the assembly.

Dennis, no I was waiting to complete the effort after I got some yard work done. I will compare what you posted vice what I have. Thanks so much for your input.
