Nickt Posted August 1, 2019 Share Posted August 1, 2019 I need some help from clever people on here please. I have a tailchaser running on two loops, linked, cab control and each loop can be isolated and run independently. I have recently been tidying up the rat's nest of wiring and think I have upset something. It's DC. Don't laugh, my controller is a H&M Duette which has worked well for the last few years BUT I now have the following issues: With Resistance set to High and Wave Switch set to Half any of my locos will run fast in only one direction With Resistance set to Low and Wave Switch set to Half any of my locos will run at adjustable speeds but no gentle stop With Resistance set to High and Wave Switch set to Full any of my locos will travel in either direction but all or nothing, just stop or go With Resistance set to Low and Wave Switch set to Full any of my locos will travel in either direction but no gentle stop Thoughts on this welcome.

Grovenor Posted August 1, 2019 Share Posted August 1, 2019 Suggest you take your Duette off the layout, connect the controller one at a time to a simple yard of track and test in that configuration. Report back here. That should identify any issue with the Duette, eliminating any influence from whatever you did to the layout wiring.

34theletterbetweenB&D Posted August 1, 2019 Share Posted August 1, 2019 Definitely worth following the advice above. Is your Duette also used to power any accessories on the layout, point motors, lighting, track cleaner, etc.; using one or both of the unregulated outputs? If so simply unplugging at the unregulated outputs may allow you to see whether the track supply then returns to normal. 1 Link to post Share on other sites More sharing options...
Pete the Elaner Posted August 1, 2019 Share Posted August 1, 2019 If you have a multimeter, set it to measure volts & see what you get across your controller terminals while you drive a loco. 1 Link to post Share on other sites More sharing options...
Crosswood Posted August 1, 2019 Share Posted August 1, 2019 Being both lazy and easily confused, I thought I would try 34theletteretc's simple suggestion first and, disconnecting my mimic panel with stud and probe point control and indicator LEDs from the 16V AC socket, all is well! I shall now power the panel etc from a spare 'The Engine Driver' dual controller with 16V AC outlet which is probably as old as my H&M Duette. Having tested it, everything works. Many thanks to all for suggestions, I knew there would be someone here with an answer. I shan't ask anyone to explain what the issue was since I shan't understand. I fear I may come back as other problems rear their ugly heads. Link to post Share on other sites More sharing options...

Presumably this happened during the 'tidying up' described in your opening post. So long as you power the point control from the independent controller you describe using from now on, you should not have a problem. What I would do is write a note to this effect and stick it on the control panel somewhere as an aide memoire. 1 Link to post Share on other sites More sharing options...
Crosswood Posted August 4, 2019 Share Posted August 4, 2019 There is wise advice on here about making notes and labelling wires - can you guess who disregarded that. When setting it all up, it made sense but going back to it now it's bewildering. The need to tidy up was prompted by retro-fitting Seep point motors to previously manual points. That's another piece of advice I ignored - fit below the board point motors before pinning down, ballasting and doing the scenics. Thanks again, much appreciated. 1 Link to post Share on other sites More sharing options...
