The tether should be 4 wires. 2 for hot and common AC... And 2 for DC motor.     Power goes to board AC & back DC. 

Headlight on yes. I will check tether values next week probably friday. Does tether wiring usually fail in the engine or tender? I will try 1 whistle and 3 bells first.

Are you using the lousy control system shown in the photo?

 

If nothing wrong, will you apply the procedure at the bottom of your post?

the problem is in the posting title..sorry. The controller in photo belongs to the customer.Can this engine be tested another way than the supplied unit in the picture?

Run it with a transformer just as you would a regular loco.  Forget that*(@(*(#& controller and box in the picture. 

 

Take shell off loco.  Place DC voltmeter on motor terminals.  Try to run loco.  Do you get voltage?  If yes, motor shot.  If no, apply DC voltmeter to output terminals of board.  If you get power, problem in tether or wires between board and motor.  If not, check the wires where they connect to board, and if no power after checking the connections there, put AC voltmeter on input to board.  If power, which there probably is since horn & bell work, problem in board.  If none, problem in tether or wiring all the way to rollers, but since headlight lights, I doubt problem is upstream of where headlight lead connects.

and the loco took off, it was a bad transformer.
