The orange and grey wires bring voltage from the track. The white and green wires feed the four incandescent lamps on the car floor.
The incandescent lamps work fine. The exterior drumhead and side marker lights do not work.
With power to the trucks sufficient to power the four incandescent lights, there is zero voltage showing at the connectors for the drumhead and marker lights on the end of the circuit board. I have tried to find a replacement K-Line board with no success.
It would seem that a resistor with the correct output voltage could be placed inline between track voltage and the marker lamps.
Is anyone familiar with the voltage requirements of the drumhead and side marker lamps?
Thanks very much for any knowledge that you may have regarding how I can remedy this issue.
