It even has little eye connectors for putting the wires. To avoid the motor from going to the main power I simply put electrical tape over the pressure pressed power connectors inside the unit. The hardest part was feeding and securing the new wire out of the unit (out the front beneath the ax power connector). You have to be careful to make sure it doesn't rub on the axle inside. Over time it could wear thing and cause a short. So my track feeds the aux connector that feeds the lights and my Lego RCX power connector. Then the RCX is always powered and controls my train.

(...) How do you get it apart? How do you like your design in practice? I would like to see pictures of your whole engine, if you have them handy. Using the track to power the RCX was one of the ideas I was considering. The other was using the (...) (25 years ago, 3-Jan-00, to lugnet.trains, lugnet.robotics)

		Re: Has anyone disassembled a 9v Train Motor?
Sooner or later I'm going to try what I talked about in another thread - pulling the motor out of the shell, and adding in a capacitor and other circuits, so that the capacitor feeds non-stop 9V to lights or other circuits, while the "main" circuit (...)

Has anyone investigated the possibility of disconnecting the motor from the pickups on the wheels so it can be powered from the top plate without driving other trains on the same track?
