dibber25 Posted October 3, 2013 Share Posted October 3, 2013 Any ideas where I can find instructions on fitting a decoder to a Bachmann GP38-2. (I know you can buy it with DCC on board, but the one I've got doesn't have that). I have checked the TCS listing and there are instructions for fitting the TCS M1 to a Bachmann GP35 which is the closest. However, the GP35 chassis is the old split frame type and the GP38-2 is different. The main chassis block splits horizontally and I've a suspicion that the motor is not live to the chassis and that therefore a simple de-soldering of the wires to the motor and routing via the decoder should be all that's needed. Anyone know if I'm right? CHRIS LEIGH Link to post Share on other sites More sharing options...
rodshaw Posted October 3, 2013 Share Posted October 3, 2013 I don't know whether this helps - the description of how he/she did the wiring comes in around 5:40. Β Β Rod Link to post Share on other sites More sharing options...

Β I've hardwired one into an SD40-2 recently and I **think** that's the same as you describe, I just soldered it in connected to the two motor wires and the four truck wires, I don't believe there's any power running via the chassis block.
