choralc Posted December 19, 2014 Share Posted December 19, 2014 Looking at the motor from above the bottom black wire is tap-screwed to the chassis and the top black wire comes up through a hole in the chassis and connects to the motor through the capacitor. I intend to desolder the capacitor and then use a mutimeter to test for any connectivity from the left and right wheels to the motor solder tags as well as the two now disconnected black wires. If the motor is isolated I will wire up a decoder as indicated in the pic. Anything obviously wrong with my thinking?/media/tinymce_upload/R2098_DCC_fitting_small1.jpg Link to comment Share on other sites More sharing options...
choralc Posted December 19, 2014 Author Share Posted December 19, 2014 I intend to desolder the capacitor and file it away somewhere. I hope I get as many views now that the pic and text is in as when it was blank! :) Link to comment Share on other sites More sharing options...
Rog RJ Posted December 19, 2014 Share Posted December 19, 2014 I wouldn't bother unsoldering the capacitor, just snip it off. The heat of unsoldering can cause damage occasionally and is best avoided. Link to comment Share on other sites More sharing options...
2e0dtoeric Posted December 19, 2014 Share Posted December 19, 2014 I think the can-end of the motor is a form of thermo-plastic. Be very careful soldering to the brush tags, as the plastic very quickly heats up into a horrible squishy mess. Link to comment Share on other sites More sharing options...
choralc Posted December 19, 2014 Author Share Posted December 19, 2014 go for it ,all ok to to mesleeve the decoder too much metal about ,watch out for space these smaller locos dont have a lot of room in themmagfan, where the decoder is indicated is where the DCC ready versions have the socket as the open cabin begins at this spot. Am definitely using a cut-down version of the insulation sleeve. Big heatshrink tubing perhaps? No maybe not. Link to comment Share on other sites More sharing options...
choralc Posted December 19, 2014 Author Share Posted December 19, 2014 Thanks for the encouragement everyone. Will do the snipping and testing when I am ready to add the decoder. Sooner rather than later. Link to comment Share on other sites More sharing options...
choralc Posted December 22, 2014 Author Share Posted December 22, 2014 Not only is this loco now chipped but I used one of the recycled ones that I had complained about before that had the less flexible wires that broke off at the solder points on the PCB. I know that it was suggested that I should return them even though they are two years old but even with my tremors I had to have a go at refixing them! Thank you again to the very helpful forum members. Link to comment Share on other sites More sharing options...
