Reply to "MTH ps2 FEF 844 triping breaker"

the FEF mth engines had a ps 2  5 volt board and were know to fail! i would disconnect the 4 pin smoke connector which connects to the ps 2 board then try to power up if powers up and not excessive amps being drawn then you problem is in the steam heater and or fan driven smoke motor. if the engine still runs ok then that's your only problem but if it still draws excessive amps with the smoke unit disconnected then your 5 volt board has a short in it and it is not repairable. i have this exact engine and i replaced my bad board with a ps 2 3 volt board which are no longer available !
