Thanks, but that didn't work.  I can't get it to move, nor can I get the lights to come on. I'm gonna go thru all the CV's and check their settings.

I have two questions regarding my SD-45. First, how do I reset the decoder to factory defaults?  Second, I bought an MRC deisel sound only decoder to add to this loco, and I'm not sure where to connect it on the circuit board that came installed in my SD-45. Any ideas?

Thanks

I finally got the shell off. I just needed to pull really hard.

Thanks for your help.

I took them out also and it's not coming off.  Is it possible it may have gotten glued?

Ok, I took the screws out that hold the couplers in, then removed the couplers and their box, but it's still not coming off.  There must be something else holding it together.

Thanks, but that didn't work. I removed the fuel tank and removed the only two screws that I saw. These screws are very short and didn't seem to loosen anything but the motor.

Any other suggestions?

I have a spectrum sd45 DCC installed. I want to replace the factory decoder with a sound decoder, but can't seem to get the shell off. Can someone tell me the trick to removing the shell?

Thanks

Troy

Jamie, how did you manage to get the shell off without damaging it? I have the same unit and can't seem to get the shell off.

Thanks for the replies.

First, yes it is a Bachmann and yes I have been looking at all the diesel decoders (and they're prices).  I'm not looking for top of the line, just something I can afford.

Second, I posted my question here hoping someone from Bachmann would respond with knowledge of what is in this loco. And whether I can add a sound decoder or if I have to replace the existing decoder with a full functioning decoder, and also what models would fit in the loco.

I have an SD-45 that came equipped with a basic decoder. I would like to change this for a sound equipped decoder.  What brand/type of decoder should I get?

Thanks

Troy
