:)Thanks all!, for your help, it has taken more time than I thought, much reading and have learned a great deal about DCC, DC, using a multi-meter and programming DCC capable locos and I believe my problem has been resolved.
I connected my multi meter in series to read amperage draw with an Arirto-Craft DC power pack 0-21 volts for the new DCC equipped Shay that would run and recorded the amperage draw .20Amps hear sound, .30Amps loco starts to move and .90Amps loco running full out.
These values are well below my NCE 2.0 amp power pack restrictions of 2 amps total and the 1/4 amp program track provisions.
The used Shay recorded .12Amps with a steady sound but no movement or increased amperage draw as I increased the voltage 0-21 Volts, so thus I thought no motor problems.

I was hoping for an easy programming solution, So I finally removed the oil, coal cover and discovered a loose orange wire from the top board to the lower board receptacle and low and behold it responds just fine,
Thanks again;
Brian

Thanks for the replies, Steve and K. I bought the power cab for my HO layout, bought the new G scale shay for display then fell in love the big stuff! The power cab is the only DCC system I have access to and it drives my new 3 T shay with no problems.

I will try and measure the voltage with my DC ( analog ) power pack. If I have read the schematic correctly green and orange are motor power to all 3 trucks.

Thank you's for the quick responses. I have reset the the CV's several times using Ops mode and service modes changing cv 8 to 8, power down, wait, re-power, lights flash 16 times, sounds come back but still no movement.
I cannot read the value in cv 30 or several other cv's such as cv 115 the whistle. Occasionally I can read the manufacturers cv as 141 and the decoder vera of .080. but no luck with anything else and re-powering between cv reads.
I changed cv 115 to an alternate whistle with both Ops and Service modes and they were accepted every time and cv 8 reset this feature back to factory setup every time.
I have another new, 3 T Shay that works just fine on the same small circle track and I can read the cv;s in service mode with no problem. I thought swapping tenders with each loco might give me some insights but both tenders sound great and move fine with the new Shay but not not the old.
Correct me if I am wrong but each truck ( x3 ) has a separate motor and the DCC board is in the oil/coal bunker?
I have heard that some of the older shays had problems with plastic gears, but I believe that these 3 T shays all have metal gears and are pretty much bullet proof? So I kind of discount this as a problem especially with both of the tenders working.
Thanks;

Yes, I have tried the switch in the NMRA and normal positions and still no movement.
Thanks

I have acquired a used 82698 3 truck shay with factory DCC and Sound. The bell, whistle, lights all work fine and it even makes the chuff sounds when the throttle is moved either forward or reverse, and the brakes squeal then decelerated. The sound/light features work with either my DC or DCC ( NCE Power cab ) but the Loco shows no movement or intent to move. Any ideas/help are greatly appreciated.
