I have an old Railking Hiawatha with the QSI electronics. I was having sporadic problems with getting the engine to run and it was suggested on the OGR board(quite some time ago) that it might be a tether problem. I finally got fed up and put an Williams e-unit in the engine and stopped connecting the tether. I was fiddling with it this weekend and wondered if I could salvage anything. I see four wires coming from the tether - red, yellow, black and white. Would it be possible to bypass the reverse board in the tender and still get sounds? Is there a method I could use to troubleshoot the boards without hooking the tender up to the engine? Should I not waste my time and just gut the tender and go with some other sound system? Thanks in advance.
