I took out the TMCC board set years ago and thought I'd never use it. So I just clipped the wires without labeling them. Once I replaced the board with PS2, the engine ran so much better, I didn't bother to use my memory on what wires went to what.

So like 10 years later now, I have my William's Challenger on the bench. I put a simple bridge rectifier inside for testing. I haven't powered it up to test yet. I'm working on the drive and thought I'd install some type of control boards. I looked in my pile and found these laying here.

I have no memory of what that board with the blue relays is from? A different engine? It has double bridge rectifiers on the bottom.

I also lost my TMCC wiring guide from when my old computer crashed.

I just looked at the ERR site for wiring and didn't know which board(s) I have here?

I have the spare wiring parts in a bag down stairs. Is it worth installing this old stuff? Can it be adjusted for smoother starts than when in that Sunset?

The TMCC board has chips installed. One says Generic Articulated. Another says RS27SA16? An addition board label is r2lc07.

& Will this set run in conventional?

Joe,

The board with the blue relays looks like an old Williams electronic reverse unit. I've pulled a few of those out and did the same thing you did, stash em' and didn't mark the wires!

Thanks! That maybe why I don't remember it? I yanked that one out and threw it in the drawer. Never thought I'd use it.

Maybe that should go back in for now? I just want to see if my drive work is better than the stock was. I tested it already on my bench. I need to try it pulling a train on my layout now.

You can run conventional or TMCC with the TMCC board set.  The pinouts of most common motherboards are readily available.  You can even have cruise by adding the ERR Cruise Commander M to replace the DCDR motor driver.

I wouldn't expect the board set without cruise to run any better than it did in the 3rd Rail engine.

You won't find that board on the ERR site, it's all Lionel stuff from what I can see.  Look for the xxx-PCB1-xxx part number on the motherboard, let us know what it is.
