Ok gang, maybe I should call this the "mysterious red wire" thread. My boat is wired at the distribution panel like the second wiring diagram in the Ariel manual as follows:

Purple: Bow Lt
Orange: Running Lts
Yellow: Cabin Lts
Blue: Misc (Anchor Lt on mine)
Green: Misc (Spreader Lt on mine)
Black: to the termnal strip then to (+) battery

But wait, there's one more. A red wire is in the wire bundle but it doesn't attach to anything in the distribution panel. It has the exact same butt connector that all of the wires use that attach to the switch panel, so it looks like original installation as opposed to add on. Only one prior owner on this boat and only for a couple of years in the 60's, and I know my dad didn't add this wire! The red wire reappears and is connected to the top of a circuit on the terminal strip, and there is another red wire from the bottom of the same circuit on the terminal strip. It goes to who knows where-- it disappears in the bundle of wires that go off into the darkness behind the bulkhead and the icebox. Sooooo, may I safely assume that this was an "extra" that can be used with the additional switch panel I'm adding, or was it for something? I'm hoping to shift attention away from "Logo Envy" to "Red Wire Envy" for those of you who don't have one.
