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
   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
