Spectrum SD40 light board

[steve4015]

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.
