See if any of the wires broke off while handling the board. You did not replace the foam with the power on, did you?
Does it work with the tender shell off?
Ant chance of publishing a picture of the board in the tender?
No sir. I removed board from tender. Only 2 wires. The main lead from Loco. and common which are still connected to board. Neither are broken. When bench tested, it works good. Only when it is plugged up to Loco. it still works but it takes power from Loco. Or shorts out power to loco motor so that it has hardly any power.. I thought maybe a diode on the board is leaking back to the loco... The loco runs fine with the tender unplugged.. The board is out of the tender now.. I will send a pick of it..
