It is equipped with a DCC Tsunami Sound Decoder. I set my MS2 to DCC and it recognized and loaded the parameters for the Big Boy. When I release the STOP there is a very quiet "squeal" from the speaker for a few seconds where upon the MS2 then goes back to STOP. Nothing seems to work. I'm curious if my MS2 is compatible with this loco? The Big Boy is from 2009 so it's not that old. Maybe the decoder is bad? It's a very nice looking unit. I guess if it is bad it will look nice as a display piece....

This sounds like the decoder is overloading the ms2. Tsunami decoders are known to be current hogs at the best of times, but either the track box is going into current limit mode or the power supply is giving up, although I would expect that to make the ms2 to reset.

Is DCC the only protocol enabled in the MS2? This is a two rail loco. No suppressors in use. There are a couple different options for DCC and I tried them all. Still the same outcome.

I was thinking the same. I'll have to play around some more and see what I can come up with.

That is impossible! Tsunami sound decoder are just like others sound decoder in power consumption. If you have Märklin old diesel locomotive V200 you can easy drive it with the MS2 without problem and V200 draw at least about 1,0 Amps! Overload happens only when you have more than one locomotive stand on the track and the power consumption overload mora than MS2 can handle with it. I believe TS did miss something here about the problem.

That is impossible! Tsunami sound decoder are just like others sound decoder in power consumption. That is not what I see on the JMRI forum. tsunami decoders often present problems for a considerable number of reasons, one of which IS high current.

I don't even have a DC analog power supply. I think my brother has a descent DC power supply; I'm going to try and run the loco DC and see what happens...

Still you avoid the real reason of why you think about else. If you use digital locomotive in scale 0 or 1 you can easy use MS2 without overload the MS2. I don´t believe Tsunami decoder makes overload by high current. Impossible! Tsunami decoder present in power consumption like others digital sound decoder too. I have never seen a decoder average over 2,0 Amps for the H0 digital locomotives.
