Hi,

New on forum. I have a Mikado 2-8-2 locomotive that is shorting out my DCC system. If I disconnect the tender (where decoder lives) it makes all the right noises (whistle bell steam etc.) but obviously no motor to make it run. When I hook it up to the locomotive I get shorted main power at about 3 amps.

I have opened the shell and no wires look pinched etc.

Does anyone know where I could get a schematic/wiring diagram for this unit?

Also, any thoughts about what could be causing this? 

Thanks, Dave
