I have a Tsuanmi- 1000 in a Mikado 2-8-2 which has been running great since it’s install 6 months ago! Yesterday I backed some cars into the yard and after working on the cars on my bench (about 2hours) Power shut off, I returned them back to the 2-8-2 but the 2-8-2 wouldn’t run.
I still have full sound capability and it still responds to it’s programmed address, so I pulled it apart assuming a broken wire but all is Ok and I have good pilot light and no fault lights so all looks OK!
The only thing that has changed now is that I can’t get a headlight and I only get the backup light in both forward and reverse. Both worked fine before!
Are we looking at doing a CV8 to 8 reset? or is there something else I may be missing?
Thanks, David. I did the CV8 to 8 and the loco jumped a little bit ahead. Also the front and rear lights flashed the 16 times as per the manual. Still won’t move even on the now 0003 address?
Are you trying the 2-digit address ‘3’ or the 4-digit address ‘3’(the reason I ask is some people include the leading 0’s to differentiate between the 2-digit address and the 4-digit address)? If you mean the 4-digit address, then you need to use the 2-digit address.
You might also try putting it on the programming track and try reading the ID and see what no. comes up. I’ve seen some situations where a decoder gets it’s ID no. changed to something odd for no apparent reason.
I’m trying the 4 digit address as thats what I had used before but I will also try the 2 digit. Hence my problem, I’m using MRC and MRC’s programming track does not have enough voltage to the programming track to use, program or read back on the programming track so I’m stuck programming on the main track.
In Ops mode (not the programming track), put the loco on the mainline track. Dial up address 00 (remove all other locos first) and program CV29=6. Then set CV1=3
Dial up the loco (3) and confirm operation. Re-enter OPs mode with the loco responding to 3 and set CV17 and 18 manually. Calculate CV17 and 18 values here. Then set CV29=34. It should now respond to it’s 4 digit address.
Thanks David, worked like a charm. Back up and fully operational. I suspect the culprit is the famous Atlas turnouts shorting when the loco comes across the two rail points next to the frog, I noticed a couple of other locos stopping and restarting at a couple of frogs but their decoders were able to reset. A grinding I will go!
Does this also work with NCE decoders or any others? Is this a problem with Tsunami decoders? If it is it looks like QSI may be the way to go!
This will work with any decoder that supports OPs mode programming. However, with my DB150, I do not concern myself with programming the addy in Ops mode…viva DB150.
