DCC Problems

Received a DN163K2 decoder for a Kato SD80MAC from Klein's today.  As soon as I installed it, which smoke started coming out of the loco.  Contacted Klein's and they will replace it.  My questions is - was it just the decoder or could it have messed up my loco?  Smoke was coming from within the unit itself and not from the decoder that I could see.  How can I check this?

Bob, try putting in the DC board if you still have it to make sure everything is OK.

Set your DCC system to Address 0 and you can run analog locos.

Actually, Bob's got Prodigy, which doesn't play the zero game.  Put the light board back in, put the engine on a loose piece of track (not connected to the DCC) and touch a 9v battery to the rails.  It'll run one way, turn the battery around and it'll run the other way.

Let me know what happens...

Thanks Lee.  I did place the loco on the program track and I got lights and the standard buzzing noise you get when you put a DC loco on DCC tracki.  Think the loco is OK.  I just might run over to Klein's tomorrow and exchange the decoder and take the loco with me and let them install it.  Keeping my fingers crossed.  Although it's way past my time period, I really like the SD80MAC's.  When my GEVO arrives it'll make a neat pair to run on Johns's system.

I had the same issue with my CSX SD80 Mac's, what is happening is the contacts are shorting out on the frame. You have to put some capton tape over the saddle insulating the frame from the decoder. Once fixed she worked like a charm.

  I have a few Sd-80 mac's also. Thanks for the hint.
