Hi Rich
         Thanks for the input I will try and use proper language this time. The TSU-1000 (Not  TSU-G1000 as I said I thought it might have been) is a Soundtraxx Tsunami Digital Sound Recorder which I am in the process of replacing for the faulty Bachmann light board / DCC decoder. I have the diagram already that you offered up for reference and it too lists the U+ (looks like a V+ too me?) for line #16, except the actual light board / DCC decoder actually has; in two (2) separate locations, a V+ (or U+)marking / connection ? I just cannot determine what these V+= or U+ control?

I am extremely interested in how you can verify a board with an OHM meter, I am not the electric guru but I am not afraid to try either so if you would, please instruct!

Anyway, I considered changing back to the factory decoder, etc. but I am not a Bachmann fan so...

Ok Folks, I purchased a B&O 2-8-8-4 from my friend KNOWING that the decoder / light board was faulty! He purchased the unit new back in 09'10 sometime and he did in fact damage to stock decoder / light board. That all said, I am replacing the bad circuit with a Soundtraxx Tsunami TSU-1000 (it may be a TSU-G1000, I'm not in front of the new decoder and forget the exact model) and have just about finished but am suffering from brainfarts, specifically what do the V+ / V- lines feed to / from on the stock decoder and which lines do I connect to the on the Soundtraxx unit?

Help is GREATLY appreciated.

Hi Westbound
                    Still not working? I've tried numerous times to get the CVs to register but nada?

Thoughts?

Hi John
              That's great news! I was going to try this tonight at the club!

Thanks for the guidance!

Hi
  SPROG is a computer based programmer for DCC decoders.

Hi Pat
      I was able to reset CV 30, no issues however, CV 8 would NOT allow me to edit the field at all (it would not allow me to "Write" to CV 7 or *)!

Any thoughts?

Thanks and take care

Hi
   My club runs digitrax and the Spectrum EM1 I have currently has the stock Tsunami decoder installed (RTR) but NO sound at this point. My problem is two fold (or maybe more depending on the groups responses):

1 - When I registered my unit (7604#) through SPROG, it took with seemingly no issues BUT when it starts, it starts at full throttle and I cannot decrease / increase speed?
2 - I DO NOT have reverse?

I have reset everything to the factory defaults, tried re-installing it as #03, etc. all to no avail?

HELP!

Thanks and take care
