AMac Posted October 29, 2020 Share Posted October 29, 2020 Hi, I have some old locos that I am converting to DCC. One of these is a Lima Class 20 (about 25 yrs old?) which was kindly given to me. The engine works fine. I have seen a couple of videos on converting this type but they a re slighting different - essentially a simple pair of connections. However the version of motor I have has more connections. I believe there is a capacitor and a pin the goes through the motor casing -everything all connected. I am nervous about connecting up as I'm sure I'll leave an electrical connection between the rail pick up and motor because I don't know what's what here. I'd really appreciate advice on what is going on and more importantly, how to connect the decoder. The decoder I've bought for this conversion is a Hornby TTS Class 20 chip. By the way, is this a can motor? Kind Regards, Alastair Link to post Share on other sites More sharing options...
RMweb Gold RedgateModels Posted October 29, 2020 RMweb Gold Share Posted October 29, 2020 Get rid of all the wiring between the bogie and motor, including the capacitor. Red and black wires from decoder to tabs on the bogie, orange and grey to the motor terminals, easy peasy Link to post Share on other sites More sharing options...
AMac Posted October 30, 2020 Author Share Posted October 30, 2020 Hi RedgateModels, Many thanks for your help. I didn't expect an answer so quickly! Yep too easy - I tend to over-think things especially when something is new to me. BUT just to make sure, are the motor terminal where I've marked in yellow below?

RMweb Premium CloggyDog Posted October 30, 2020 RMweb Premium Share Posted October 30, 2020 (edited) Yes, those are the motor connections. As RedgateModels said, grey and orange wires to those, red and black to the bogie pick-up contacts. The wire coils, rods and the capacitor atop the motor can all go. Done a fair few if these myself, quite straightforward. Edited October 30, 2020 by CloggyDog Link to post Share on other sites More sharing options...
RMweb Gold geoff Posted October 30, 2020 RMweb Gold Share Posted October 30, 2020 NO NO, that is the wrong way round. RED AND BLACK TO THE TRACK, GREY AND ORANGE TO THE MOTOR. Geoff 3 Link to post Share on other sites More sharing options...

AMac Posted October 30, 2020 Author Share Posted October 30, 2020 Hi Geoff and CloggyDog, thanks for confirming the terminals and help my understanding. I'm just getting back into railway modelling so I've done a fair bit of reading but still virtually no "doing"! Thanks again to all for all the advice, Alastair Link to post Share on other sites More sharing options...
