Lionel CCs2 6-11154 Schematics or Diagrams

Hello All

I recently smoked my engine due to a unfortunate derailment. Since then, I updated all the circuit breakers on the layout.

I found a cap C10 blew on the Bell coil drive PCB. Since I do not have Schematics or diagrams, I am left to black box theory. I have a bell driver on order and have a radio board from a earlier purchase. I tested the tender on another engine and everything is good there. The radio board responds to open the rear coupler only nothing else. If I had drawings or schematics I could poke around with my scope or volt meter to get a clue to what else is damaged. Any ideas would be thoughtfully considered also.

Regards

John

I'd put the R4LC in first with the bell control board and see where that leaves you.  If that fails, and you still have a short, I'd probably suspect the DCDS.  A quick diagnosis is to unplug the large black 6-pin connector and see if the short goes away.

I have a bell control board in the mail, when I get it I'll take a look.  I'm sure you understand that I'm not inclined to take apart one of my CC2s locomotives just to see what part it is!

Pretty sure that L718 would be the date code, in this case 2007 the 18th week.  I can't find a 66RC anywhere, so I don't know what that is.  I'd guess a FET, but that's just a guess.

My feelings exactly I do not want to have two of these apart at the same time. I just purchased the other one, on eBay last week. I’m hoping to double head them with a very large consist. 

Does TMCC allow two engines assigned the same ID? I’m hoping so that when I use the bell or steam effect they both do the same effect. If I lash them only front engine whistles and rings the bell.

You can use the same ID, though I think they typically work better in an MU configuration.

For Legacy, you can configure an MU so that both locomotives whistle and ring the bell, but only one will have crew talk.  Also, the lighting usually works better configured as an MU, though since the CC2s is early Legacy, it may not be perfect.

FWIW, I just picked up a second one, I think they'll be really boss running together.  I'll have to figure out how to renumber one of them, though all the lighted number boards will be a challenge.

The cc-2 uses a RCDR not r4lc. I have the board  in hand that you have in picture and I don't see those components  on my board. You have a better overall picture of the board I can see.

Right you are Bob, I actually ordered one of those RCDR's to have a spare, so I actually should know that!

Here's the bell control board, I'm not seeing those components either.

However, if we look at the smoke fan control board, we have better luck.

The posters picture does not  look like  the smoke fan pcb board ,close but not correct. C10, he claims to be a cap. but on the smoke pcb board it is a resistor r32

It may be a bell board. I have one thats similar though not exact. I assume there were changes along the way.

Before installing a new or repaired board make sure you check the bell coil. It should read about 100 ohms. Yours may be shorted. I got three bell coils and two had their leads ripped out. The coil is wound with wire thinner than your hair so reattaching them took a bit of effort. The way they are assembled (read poorly) its possible the two leads got shorted under the tape.

If your coil does read shorted you may be able to fix it after removing the tape. 

BTW on my board the cap is labeled C3 but in the same location. Its a 10uf, 106C.

imageimageThis is the I am using. They are different. One thing I noticed is yours seems to use   outside rail ground while mine has both outside rail and signal common. My bell board does not respond if Legacy common from the RCDR is not connected to this  board. Makes me wonder if your board will work directly with a TMCC signal vs Legacy.

The regulator appears to be a TI M2937IMP-5.0 low dropout 5V regulator, the device marking is L71B for this part.

The cap is a 10uf tantalum, don't know what the voltage is, but probably in the 16-25 volt range from the size. 

Yes, I just got my bell controllers in.
