EMD GP-9 DC Wiring Harness
This wiring harness consists of 17 LED lights prewired with the appropriate resistor values soldered in place to give scale lighting for the various applications throughout the diesel. 7 LED's are mounted in a specially designed holder that glues in place right behind the installed lenses ( Red Caboose GP-9) on each end of the diesel. There are 2 each LED's for the main headlight, 1 LED for the 2nd headlight, 2 LED's for class lights, 2 LED's for the number boards. The overhead LED and 2 LED's are wired for the ditch lights that are mounted separately. There is a circuit card assembly (CCA) that controls the direction of the lighting and keeps a constant voltage to the LED's under any condition. When the train is stopped the lights continue to stay on for 2-3 minutes without any power due to the large capacitors on the board holding charge. This is a neat effect when the train is stopped with all of the lights still on. Very protypical. It is easy to do this with a DCC controlled train but this is the only way to do it with a DC controlled train. The lights are labeled to help in your installation. Only two wires (+) and (-) need to be soldered to the same terminals for your motor or motors.
