Atlas “F” Series Led Wiring Harness Description
This new O Scale wiring harness includes a circuit card assembly (CCA) with a LED wiring harness for any O scale EMD "F" series diesel. It was designed for the older Atlas "F" series diesels but can be used as is or modified for any diesel engine including "E" series units. It includes 11 different LED lights that can be mounted in the housing. There are 2 headlights, 2 ditch lights, 2 overhead lights, 2 classification lights and 2 number board lights. The LED's are soldered to the harness with an appropriate amount of magnet wire to mount the lights in the shell. They are also tagged to help you identify the appropriate lights. The individual lights have specific resistor values soldered to the lights to give a scale illumination for the area to be lighted. ( Different resistors can be soldered in place to increase or decrease the lighting according to your desired effect.) There is a single headlight and also a working MARS light that has 2 LED's that are controlled by the circuit card.
The circuit card has 4 capacitors on board that store power and when the train is stopped the LEDs will continue to shine for several minutes before power has bled down. This is a neat effect with the train at a standstill with the lights working especially for a DC powered train.
The circuit card is easily mounted in the shell with only 2 solder joints required. You do not have to worry about polarity because a bridge rectifier is built in on the board that accepts either positive or negative leads. With a soldering iron and a hot glue gun the harness and circuit card assembly can be installed in approximately 30 minutes. This unit will work on DC or AC controlled trains. This is the wiring harness you need to bring older trains up to a more detailed appearance. There is more lighting on this harness than is supplied on even some of the newer models.
