possible DCC system problem?

First off BRASS is a PITA. The whole locomotive is a conductor. So you have to be real careful in how you run wires and mount decoders.
The trucks can sometimes touch the frame and cause shorts. I have seen where the brake shoes on a locomotive would touch the wheel(s) and short. They can even short out on the track if they hang to low.
You should ALWAYS try your locomotives on a program track after working on them, no mater how simple the repair was. That has saved many decoders for me. The brass units get check and rechecked, then checked again, then they go to the program track.

I think i agree. The curious thing is that the previous decoder, even though it would behave hay-wire in the E44, did work, and it worked perfectly fine in a regular atlas engine. I changed nothing other than plugging in a different decoder to see if the problem would go away.

I'm going to have to search the whole engine again. I added additional contact pickups which could also be causing problems. I'm starting to wonder if there is a way i can make sure the whole engine is electrically isolated.
