Loco Sounds

Steve,

I do not use the NCE system or the breakers. To troubleshoot the system a few simple steps seem in order.

Take the PSX breakers out of the circuit> Replace them with wires for these tests.

If the sound goes away then contact DCC Specialties for help with the problem.

If the sound does not go away then start taking DCC engines off the track and see if it is all of the engines. 

If it is all the engines then disconnect the booster from the track and connect it to a isolated track with a DCC  engine. Check for the noise. If the noise goes away then it is in the layout wiring or stationary decoders.

If the noise does not go away then suspect the booster or the power supply.

Hope this helps!  Good Luck,

John Green

If this is a sound decoder making the noise, I usually find that the capacitor is missing or installed reverse or on the wrong wire coming out of the decoder.
