About the 470 ohm resistor from r2lc headlight output to ground. Is this needed with the ERR a.c. commander board, reason I'am asking is because it is shown on the board connection diagram but not on ERR commander diagram.
Original Post
The original Super-Chuffer needed a resistor, or even better, a .01uf cap across the lighting output of the TMCC package. However, the Rev. 2 version of the Super-Chuffer has that capacitor on-board, so it's no longer needed, and the instructions that come with the Rev. 2 boards omit that requirement.
The ERR AC Commander, DC Commander, and Cruise Commander all do not require the capacitor. The ERR Cruise Commander Lite does require the capacitor as the loads were not put on that board. Any stock Lionel TMCC locomotive or other locomotive that uses a standard Lionel R2LC/R4LC will require the load capacitor for the original Super-Chuffer, but not for the Rev. 2 as previously stated.
The capacitor is to trigger the lighting triac, it expects to see an incandescent bulb that provides a load, if it doesn't see a load, the lights don't light or will flicker.
