Soundtraxx Tsunami issue

[Wiredup]

I'm using a N-scale steam Tsunami kit on my Bachmann J Class and have not yet installed the capacitor that comes with the kit for dirty rails.

The decoder seems to work well for movement and lighting, but it does not actuallly make sound. In fact, it will make sound after you first turn on the layout, but after a few chuffs it stalls out, sits for a second, then comes back to life and runs like a clock, but does not produce sound.

anyone else come across this?

Nope... A few guys have the steam Tsunami's down at the club, but I haven't heard of this problem from them. Any chance it is one mute (F8)? Possibly a defect and warranty will replace?

I have several N scale Tsunami decoder equiped locos. Until I got a capacitor installed they did not perform too well.
I now use surface mount caps if space is a problem. I use 2 or 3 100 uf wired in parellel. This sure helped my locos.
Most of the time the loco will just be dead, I have never ran into one that would shut down then come back to life without sound.

I have one in an HO steamer that acts weird some times. Last night the sound worked fine but no movement. I unhooked it from train / no load, it it did fine. I hooked it up again and same problem. Some times it will run great. sometimes it will start fast go a couple inches and stop and repeat this until I shut it down. Sometimes when it is running and I slow down the sound stays fast. Needless to say I have bought my last Tsunami. I recently got a Digitraxx with a sound bug. so far my only complaint is it is not loud enough. It didn't cost me $120 either.

Do you have the capacitor installed? if you do try using a larger value capacitor . Like a 2200 uf. Also is the decoder a micro (TSU 750) or a TEU1000?
If it is a TSU 750 try mounting the decoder on a weight or some metal for a heat sink.
I have installed so many Tsunamis I have lost count. I have had very few proplems. Most were mine.
