Lionel 8632 Steam Engine won’t run

Called makes a electronic "E" unit for about $60, I've installed several of them , they are durable and pretty straight forward to install. But if you'd rather not spend that much you can install a bridge rectifier however you won't be able to change directions.

Thank you for the response. The cost would be reasonable.  Do you have a website for the part?  

Charles, Did you mean Dallee?  If so which unit is the one you refer to.  Thank you.

Dallee makes good stuff, but you can buy an entire set including that style of engine for $60, or buy just the engine for $30ish and roll the dice that the electronics will be good.  The sources for rectifiers change often - I'd suggest searching ebay or Amazon - they can be found for just a few bucks each.  Be sure to find something that will fit.  The ability to change direction can easily be added with a DPDT switch, but doing so will require physically throwing the switch to make it reverse.

Mallard, thank you for the advice. You may have the same disease that I do, it’s called the impulse to fix things.  Doesn’t matter what it is.  If it’s not working I want to figure out why and fix it.  Must be the challenge of it.  I’ve been that way since forever.  I don’t really need this unit.  I have way too many steamers and actually have another 8632 running on my track now.  When I purchased this steamer I wanted the whistle tender that came with it however it turned out to have a damaged control board as well so it doesn’t whistle. I had the same issue with my other 8632 tender. When I went to replace that tender’s control board I found that they no longer exist.  I have no knowledge base about modern control boards that can substitute for the original ones.  Advice I‘ve received is usually something to the effect of go to the internet and get this or that and just put it in.  Obviously those giving the advice have experience that I don’t. It was too confusing for me.  All of that said I would like to install an e unit that gives me forward and reverse.  If you have any advice about a fix for the tender I’m all ears

This is the non working control board from the tender that came with the Lionel 8632 Steamer

Read the numbers on the face of it- that's the part that failed.

More on the tenders that came with my 8632’s.  One doesn’t work at all-that’s the one in the prior photo.  The other whistles all of the time.  See attached video.  Any ideas on the one that runs continuously when power applied?  Thank you in advance.
