I have this engine and I'm converting the headlight to an LED. There's a plug that is attached to the headlight. On one end of the plug, there are a brown and a black wire, I've attached the red wire to the brown and the black to the black. Problem is I'm not getting any light when connected that way. Connecting just the LED to power, it works fine. Any ideas?
Flip it around. LED's only work one way. Maybe it's wrong?
