I don't know which ERR board kit my repair shop used, and unfortunately he'll be unavailable to answer that question until Wednesday. The other Loco that won't program is a Lionel B&O EM-1 6-28051. To program I've:
1. Powered off the track
2. Moved the Run switch to Program
3. Placed the loco back onto the track and powered up the track
4. On the Legacy Cab, press ENG, 76, SET. (Not getting any response from either loco after pressing SET).
5. Power off, remove the loco, flip the switch back to Run, return to the track and power on
6. Pressing ENG 76 on the legacy cab, no response from the locomotive. Press ENG 1 on the legacy cab, responds immediately.
On my EM-1, I can turn the front light off using the AUX 1 button on the CAB, however for the Mohawk with the ERR board, I do not know how to turn the headlight on and off, it's definitely not responding to the AUX1 button. My repair guy recommended trying a reset by doing this: In program mode, Press Engine, Engine number (in my case 1), SET, AUX1 and then #4. However, on my legacy cab, I press Engine, 1, set, AUX1 and the keypad does not change to numerical mode.
