Installed a new engine board, using existing tender board and the locomotive simply will not come up in DCS.  Runs fine in conventional.  Performed the factory reset (in conventional) and it took, got the two toots.  Sounds, coupler, smoke, bell, whistle work fine in conventional but it will not respond in DCS.  Could not even test the boards on the PS3 Test Assembly, could not get any of the lights to come on (while on Test Assy.).  When advancing throttle (in DCS) I get current, not muck, which means the boards are seen.

Any ideas?  Possible defective tender board?  Can the tender board be tested without the engine board?

Update:  Tried loading the sound and chain files - no luck.  The Technician Loader program said"engine not on track".  Tried numerous times, even insured the serial cable is connected and active on com 3, no luck.   Double checked the switch positions on the Test Assy.

In reading the instructions for the PS3 test Assy. it says you can test the tender board - but it does not say if the tender board is connected to the test assembly without the boiler board.  My question is:  Can you test the tender board by itself?  I am guessing you can not.

Looks like thi 261 needs a tender board.

Yes you can test the tender board separately, but it will only generate output the tender would have.  Does the Tender board have the DCS jumper installed?

Yes it is possible the Tender board is damaged and will not see DCS.  G

Double checked the board - no DCS/DCC jumper.  The box end definitely says Protosound 3.  Reading the description on the MTH web site it definitely says at the bottom of the description "DCC".  It does not mention DCS.

John - looks like you hit the nail on the head.  This locomotive operates either conventional or DCC.

Checked the bottom of the tender board, near the heat sink, in a corner are 4 holes, where the jumper connector would be.  There NEVER was a jumper connector installed on that board.  My guess is that the locomotive was never run in DCS.  Awaiting to hear from the owner.

I double checked the jumper location with MTH  photos of the board bottom.  Next to the 4 holes is the word "Track"next to the heat sink.

on the page I believe the list of features was cut short. So you just see the DCC at the end.

Why go back to DCC when I have DCS!
