Replacement motor

[Richards Grandad]

Just bought 2 off worm & worm wheels hoping to replace worn gear on axle , along with that l bought 2 off 0-6-0 motor and retainers (which l thought were amazingly cheap at just under £3) these have come with a 4 point plug attached .

Original Thomas 0-6-0 doesn't have this plug (black lead ,grey lead, red lead ,pink lead) l assume l will be able to remove solder join some of these leads to get chassis working on track , have put power to motor and am happy that it operates as it should ,it's just that on track this plug is coming into operation and chassis is static , l probably would be able to work it out , but thought it more appropriate to get answers on here?

Which leads need joining to which ?

Thanks for any answers

Of the 4 wires attached to the pins, 2 come from the wheel pick-ups (red and black) and the other 2 go to the motor contacts (grey and orange).

If you have no intention of moving to DCC control in the future, cut the 4-pin connector off and join red to grey and black to orange, temporarily at first while you test that the loco runs in the expected direction and, if not, reverse the connections before soldering.

THANKS Going Spare ,save me a bit of time. Thought it could only be a DCC thing.

Surprised both gear and worm wheel were both plastic on original , glad to change to plasticnylon with brass worm wheel.

THANKS again

Agree. Red and black are your pickups. Red one side and Black the other. Connect Red to Orange, and Black to grey. If you connect the Red to grey and Black to orange, Thomas will run the opposite way than he is supposed to. If you connect Red to black, you have a dead short and nothing will work, you will trip your controller.
