Hi fellow train lovers I been stumbling on a intermittent problem concerning my mth board ps 3 I had to open the shell to clean some excess smoke fluid. I also un plugged the conections and molly connectors to spray contact clenning fluid on all components wiped it all down with many q tips and I soldered a broken head light wire I wire tied everything back. Then I placed the train on track only to find when I applied power to track the train will start in conventional mode. So I rest the engine to factory settings. This is when I lost the train completely. I tried many time to add engine and finally the hand held controller showed that the new engine was added then I applied forward throttle no movement in either direction backwards/towards. No horn/ no bell. I did get it to run on dsc for a while and then I lost it again!! Now I’m back to square one as the engine is only starting in conventional mode. Ok I know the smoke fluid was a big problem and I’m hoping that this will eventually stop after Time. Or maybe I have a short some where. Or I need a new board? Mth does not sell new boards to individuals only dealers and the future is uncertain for mth. So I need a good service shop to fix my trains and I need access to parts so I can learn to fix my trains myself. Does anyone out there have some answers for me all my equipment is mth.
