Hello all,
I have 2 Bachmann Spectrum 4-4-0 HO locomotives. One of these engines has a Tsunami Soundtraxx decoder, the other has the standard Bachmann decoder.
I doublehead these locos nearly every time I run them. I am using a DCC layout (MRC Prodigy Express).
Previously, I had these two locomotives in a consist and I had left them in a consists for months. They worked perfectly in said consist; the number of which was 8.
I had adjusted the speed curve on the Tsunami to match the Bachmann.
On the date of this post, I cleared the consist to have both trains run independently. The loco with the Tsunami worked perfectly upon readjusting the speed curve.
The loco with the Bachmann decoder now will not respond to any commands (The loco will not run on strictly DC powered layouts either).
I know for a fact that the problem loco was address 4.
Things I tried include:
1. Reset the decoder with CV 8 to 8 and CV 30 to 2.
a. I know that most Bachmann decoders are Lenz decoders and as such setting CV 8 to 33 is sometimes necessary to reset. I have done this as well.
2. I have set CV 19 to 0.
3. I have attempted to clear the consist again.
4. I have left only the problem on the main track and tried to program on the main to address 0000 in an attempt to reset with this address, then cycled the power.
None of these steps have worked. I have tried all of these steps on the programming track and the main.
The only guess I can conger is that perhaps there is an issue with the CV relating to the address of the loco or the decoder is fried.
Any and all pertaining advice or comments are welcomed.
Happy rails,
Brandon

I have done some research and thought that the motor of the one train just needed to be broken in, so I have spent most of last night breaking it in and the train still will not respond unless I apply a speed step higher than 8. I have checked the CVs and have concluded they are all set correctly and I am still have this problem with the train not moving until speed step 8 or higher. Normally I would conclude that the motors are just not the same, however I have 2 other spectrum products (A dash 8 and a 45 ton switcher) and they both act exactly the same as the one 4-4-0 and will not respond with movement but only noise until speed step 8 or higher I have also spent time breaking them in. I also have another bachmann dcc equiped train not a spectrum product and it runs smooth as can be from speed step 1-28. So please someone tell me why these trains do not run unless speed step 8 or higher is given. I can not seem to figure this out. Any advice is welcomed.
