So I got this beautiful engine, cheaply since the original owner said his track breaker would trip when the smoke unit was turned on. Im a lionel guy, but have a MTH TIU and remote ordered and on its way.
I opened up the 844, pulled the 4 pin connector for the suspect smoke unit. Put 3vdc on the motor and it spun just fine, next measured the resistance of the smoke heater, 9 ohms, I think thats normal. Meaured rollers to frame, infinite resistance. So I will not know for sure till I get the DCS installed, but I did try conventional and it tripped the legacy powerhouse. From what I see, Im thinking the PS2 board is gone.
What do you think?
