Just installed ERR CC into a steam engine 4100 Frisco convent Lionel. Runs fine but when changing directions the front headlight will stay on. You can turn both lights on and off with the AUX button. This being the only steam I have TMCC is this normal. Code is set for 4. The AERO train I converted from PS2 to ERR CC will turn off the headlights and turn on a Red LED I installed between the headlights for reverse. Its code is set for 8.
