DC Commander/Rail Sound Issue

William ChurchOGR Forum Member SUPPORTING MEMBERDIGITAL SUBSCRIBER

Just completed my first Command Control upgrade of a William Train Master with a DC Commander/ RailSounds install. Everything went find until the RailSounds board, which I had fixed with double sided tape to the DC Commander board (not a great idea!) shorted out against the DC Commander board. I lost RailSounds but had everything else, lights, direction and couplers. Thinking that the Railsounds board was fried, I ordered a new one and installed it with a new harness but no RailSounds! Is it possible that I received a bad RailSounds board or should I be looking at replacing the DC Commander board?

Try connecting the RS board on the bench with nothing but power and speaker. You should get sound and be able to control the horn and bell using the transformer. Do that with both of them.

You also could have cooked the serial data line out of the DC Commander, that would be on the R4LC, so swapping that out might be where the failure happened.

Gunrunnerjohn, thanks for the reply. What type of voltage does the RS board expect? I put a meter on the red/blk coming into the RS board and get zero.

The RS board gets track power, if it's getting nothing, it's going to be very quiet!
