Where can I find the wiring connections for the light board on a Spectrum SD40. The front headlight wires (blue and black) are disconnected and I can't find where to reconnect them to.
Connections are marked on the light board. The markings are probably on the underside as installed.
L+ is Light positive perhaps is the blue wire
L- is Light negative perhaps is the black wire
Bachmann does not adhere to wire color codes. You cannot depend on wire color to determine it purpose. You will have to test.
