What DCC system do you have,

What DCC system do you have, kind of important.

I use a Digitraxx

I use a Digitraxx DB150 SuperEmpire builder.  just found out a friend of mine indicated same happened to his Bowser C630, ran well for a good time and then same thing happened. Issue with the tsunami board. Sure hope this is different, but does not sound good.

When I have had problems, and

When I have had problems, and my buddy as well, we reset the command station, below is various resets, we did the OpSw:39 reset.  The reset worked well for me and my friend, prior to reset engines were acting sporadic, after the reset they worked fine.

This is for DB150 but go to your manual, I think its almost the same for the CS100: [check your manual]

There are times when it makes sense to reset the Super Empire Builder. 

Because this is a system reset, there are special instructions: 

There are different levels of system reset. 

OpSw 36: Clears all mobile decoder information, including locomotive consists. 

OpSw 38: Clears the locomotive roster (such as when you receive a "slot=max" error report). 

OpSw 39: Full reset, clears all internal memory states. 

The factory default setting for all DB150 option switches is t or "thrown"

Maybe my original post was

Maybe my original post was not clear, but it is only one engine in an entire fleet behaving this way, it is not a system issue. I was in contact with Intermountain, at first they thought it might a speaker defect drawing too much power ( they said this can be quite common) and we went through a step by step analysis unplugging all the connections to see if something can be isolated. Nothing was. In the end the unit is being shipped to Intermountain for warranty repair on either the motor or the tsunami board. Will keep you posted when I find out what the specifics are and i must say the folks at Intermountain were very accommodating and a pleasure to chat with. Thanks all for your input.

I would like to hear the end

I would like to hear the end results because of the mysteries of DCC it's often difficult to say what the culprit is.  In one location on my layout, I had intermittent pick up and I couldn't figure it out.  My friend traced it to a suit case connector we had used, took the connector off, soldered the joint and we were good to go.

My theory on suitcase connectors is they work better when all wire is stranded, I used household #14 wire for my power bus and the connectors don't work as well with solid wire.

Thanks rsn48, will post when

Thanks rsn48, will post when i get some information. I use the suitcase connectors as well but it is all stranded wire. There is a learning curve to be sure, sometimes fun, sometime not. Either way sharing this type of info is great.

Had this same issue on a late

Thanks duckdogger,  I did

Thanks duckdogger,  I did have the shell off while running to see if there was something mechanical or excessive heat. The board IM uses has plugs for the connections. Maybe one of the plugs were defective to the point for intermittent running? While problem solving, I did check them one by one and they did seem to work. Fiddling with them did not change the performance. There was nothing obvious that looked wrong.  I have had the situation you described on another unit where my soldering came loose from a truck pickup. Anyway the locomotive is now enroute to the service shops in Colorado, unfortunately not under its own power!

Well the solutions are coming

Well the solutions are coming to a close.  In the meantime I have had another unit from another manufacturer also with a Tsunami board and basically the same thing happened.  On the second unit, a friend of mine had exactly the same issue with the same model locomotive. To make this story short, both decoders went boobies up, and both manufacturers totally honoured their warranties, and one even paid for my postage. Thanks Lee!  That was awesome!  So back to hauling freight on the Grimsby sub. Case Closed.
