Lionel 8689-110 Electronic Reverse Circuit
Posted by Leverettrailfan on Wednesday, May 30, 2018 5:16 PM

I have a 736 Berkshire that has been rebuilt with an electronic reverse unit (Lionel Part number 8689-110). Unfortunately, it seems to be dead, since the locomotive will not run, or reverse. The motor is in working order (I can bypass the reverse unit, and get the loco to run), but the reverse unit doesn’t, er, reverse! 

Seems like this part is neither cheap, nor particularly common, which makes me pretty darn sure that it makes more sense to just convert it back to an electromechanical reverse unit, but I can see that soeone put an awful lot of work into the wiring. Is there any hope in possibly getting it going, troubleshooting and finding a defective component, and replacing it? Or are these things irreprable? I mean, they can’t be easy, but if you can fix simple computers, then something like this ought to be reparable too, if the components are still available (which is unlikely, if they were very specific ones). I doubt it is ‘worth the trouble’. But, I wanted to ask, before I butcher this setup and kiss the possibility goodbye once and for all.

"If it don't work, then gosh darn it, get a' fixin!"

Can I fix trains? Mostly. How long have I been doing it? Took me years to get much success beyond the "taking it apart" step. Where am I at now? Well, does she run?
