Well, shoot, I've been trying to install an NCE D13SRP decoder in my P2K E-7 but no luck so far. When I plug it in so the black wire is on the left top pin (looking down on the decoder), I get an immediate short. When I reverse the plug, I get the engine running way with no control. It works fine on DC. I've tried two different D13 decoders and get the same results so I know it's not a bad decoder. Is there something special I have to do with a P2K E-7 to get the decoder to work? I'm baffled at this point. I've talked to Tony's and they say it's a problem with the engine but they (nor I) have any idea what it could be. Thanks for any tips.

Hi Dave,
Thanks for responding. The engine is for sure isolated from the frame. I checked that with a meter. It does have a light board for the Mars light with a bunch of diodes and capacitors but, without a schematic, I have no idea what they all do. According to the guys at Tony's, this shouldn't be causing a problem with the decoder but I don't know if that's really true. Since the 8 pin plug is part of the light board, I wouldn't know what to try disconnectiong to prove this. I'm waiting for someone at Walthers to give me a return call to see if they have any information.
