I realize I'm a newcomer here, but I am a journeyman electrician for the last 22 years. The color code standard for DC (direct current) wiring is green=ground, black=negative and any other color (in this case red) = hot, or positive. Hi guys!

Reason: possibly confusing and don't want to be. I like this place.
