This kit has had a few issues during its last manufacturing run. One known issue with our lighting kit is this: The “B” wire coming from the power supply is known to have been wired wrong from our manufacturer. If nothing lights up when testing out your lights before assembly, please wire Red to Black and Black to Red while connecting the “B” wire to the “J” wire. This should solve your problem. This problem has an effect on the Bussard PCB LED lights not working when the motor runs due to a power issue. Try this and check your LED lights. Please be sure that the open wires during the connection testing DO NOT touch while the LED lights are plugged in. This will pop the lights and they will not work. Thanks. Hope this helps.
