Need Help With an Electrical Failure

That era e-unit was not the best design, and would often burn out.  Unfortunately Lionel no longer has the board.  Best bet is to put a rectifier in and run it forward only.  

Isnt there also an on off switch for the direction? Or direction lockout?

I said it was one of the wires because I accidentally put to much smoke fluid in and it burned something in their

Yes their is but that’s not the case, it indicates if you go forward or backward with the lights on the back and front but it won’t move

Are you sure I mean their has to be another way I know that I accidentally put to much smoke fluid in and it caused that to burn. Their has to be another

When I accidentally put to much smoke fluid in a smelled burned wires after it broke

Which smoke fluid brand exactly? Some brands are non-conductive so they should not be able to damage components. If you already have it open, do you mind snapping a few photos?

No problem here’s the smoke unit and my engine.

Well, the smoke fluid should not cause any problems. The red wire right in front of the firemen seems burnt. is that the wire you were talking about? It seems like your electronics are fine since you can blow the whistle and the lights do work. Do you hear the smoke unit's fan blowing when you turn the engine on?

 

A close up of the electronics would help since it's hard to assert which wire does not look right.

That could be the wire. Also my smoke unit is not fan driven it’s just the usual puffing smoke unit you see with conventional sets from the early 2000s. And sure I’ll give you a better picture soon 

Ameen you still need the picture my phone is charged up

That wire looks like it's going to the switch. It could be that the switch is broken, but that's highly unlikely. Have you tried investigating the smoke unit? Does it smell burnt out?

Smoke unit smells fine it’s in the middle of the e or rev unit 

Looks like things got a little hot....

Turn your phone sideways for better photos. Upright is pretty much only good for selfies

Also I think a shot from directly overhead will be best. I know it eats data, but the more photos the better. Also after one loads and you get "success", a new line and checkbox appear mid-box "insert large size" check that. Some phones don't open thumbnails at the bottom. (also at the bottom of thumbnail box in blue, a second chance to insert large/med/sm.  If you edit, you can insert, reload, add,etc.

  That wire looks kinda cooked to me too; I can't Dyspute that 😂 It's wrinkles stick out like a sore thumb. It might be ok, soldering melt, or overtaxed by the issues at hand.

Is that sw. for smoke on/off, or program/run? (it is your lock out too. throw it to pgm. while loco is in Ñ and you go nowhere, but other features may work. If fwd when thrown, always fwd. etc.

Start by unplugging and/ or turning off smoke. Tackle running 1st and then worry about smoke later.

Good catch! Yeah, those do not look in very good condition and I am pretty sure those have something to do with the motor.

When you try to power it on does it feel hot? If so then that is the bug for sure.

 

Can you get a close up of that component in particular? Also, check if you see any melted plastic around it. Since those do get very hot when they break down.

I actually didn’t know that. When I get back from the dentist I’ll check it out.

My bad for the picture just started this account not to long ago. Still getting used to some things. And yea I’m gonna do running it first, the engine looks good with or without smoke so I’m good.

Yep.... Don't think Ive never been the new guy too   

Wow, toasty. If you want to attempt a repair just to learn and explore, it  won't hurt. But I'd consider hunting a board to use or wiring in a bridge rectifier myself, trying a repair, and saving it for backup if you succeed. Start writing down the numbers on the black parts with metal heat sinks. It might do no good as they don't always use marked parts or normal numbers, but trying can save some hassle figuring things out . 

If you can once done with #s, wash the board in hot water, maybe with a little dish soap in it to remove the oils. Pat & shake & air dry fully (it's ok, believe me. Ive ran boards and even BIG mother boards thru industrial dishwashers a hundred times (turn of the chemicals if you use one of those and fasten/clip it to the racks in home machines.😁)

I have to cut it short for now. I don't argue when insomnia lets me sleep again.😴

I know it’s the next day but I didn’t get to see if it was hot or not I’m gonna do it now

Ok well it’s not hot but it is burnt, so is this the part that needs replacing 

So does anyone know what I need to fix or replace 

The first thing you need to do is figure out what happened and why?   The smoke unit filling had nothing to do with an electrical short / overheating like that.
