Disregard this post, found the instructions on this site elsewhere, and should have searched first. Thanks for the very detailed instructions. My suspicion was right the colors do not match NMRA standards.
Does anyone have a wiring schematic for the HO Athearn Genesis Challenger? I am trying to install a new decoder in it, and have found that the motor wires are actually blue and yellow (tested), but I want to make sure I am right on the front and rear lights before I blow up anymore LEDs. The headlight appears to take green and white, and the rear is hard mounted to the old board (not worried about this one). Obviously, this Challenger does not follow the recommended NMRA wire color standards. Thanks!
