[C320-list] Anchor light problem

[jackbrennan]

Thanks, Gerald.
I have the schematic, and I'm just as confused.
If Graeme is correct, it sounds like I would have to lift the mast to get at the wiring. That's crazy.
I think I'll just use a Davis LED light to hang off the boom. I think that's more visible, anyway.

I'm looking at a schematic for "Mast Light Wiring / I.M masts," with a revision date of 5.17.93.  It agrees with Graeme of the ground wires all joining into one common black wire going to the panel.  But, tracking the power wires for the anchor, bow and deck lights is amazing!  For example; the anchor light wire progresses - in splices - from white, coming from the panel, then to green, and yet again to red going to the top of the mast...

Now maybe I'm misreading the diagram.  I am most certainly NOT an electrician, but it looks like tracing the circuits from beginning to end is going to be a challenge.  If you need a copy of this particular schematic, I can try to send you a copy of mine, or you may be able to get one from Catalina.  The drawing number is: 320-72002-1.

Good luck
