Hello all:
I am having some trouble with my cabin light wiring in my 1976 C30 #173. I looked at the wiringdiagrams on catalina30.com, but there is some difference in what it is supposed to be and how it is wired. According to the diagrams, the wiring should be as follows, and I'm showing how my boat appears to be wired:
Catalina Wiring Diagram My Boat
Black Boat Ground Running Lights
Green Mast Ground Anchor Lights
Blue Cabin Lights Cabin Lights
White Anchor Lights Ground (Boat & Mast)
Yellow Bow Lights Spreader Lights
Orange Spreader Lights Not Installed
Red Running Lights Running Lights
When I was taking apart the old switch panels, I made note of where all of the different wires were landed, and that's where I came up with how mine was wired. I should add that when I originally looked at the boat, none of the lights worked. I assumed that it was because the battery was dead.
Another note: All of the cabin lights have a blue and white wire coming into each of the fixtures, which further bolsters my assumption that white is ground, but that doesn't match the diagram and the lights don't work. I'm sure that the blue wire is for the cabin lights...I verified that by testing it, but I don't get continuity through the white wire. I also tested the lights using the black wire for ground like the diagram shows, but that didn't work either. So now, I'm thinking that maybe my boat is wired differently than the diagram shows (I have no orange wire for the spreaders).
Has anyone ever seen this before? Any suggestions?
Any help or advice would be greatly appreciated!
Mike

At this point, all assumptions given above, you physically have to trace the actual wires from Point "A" to Point "B" and find your break. Start at the panel and go to the first fixture or start at the first light fixture and trace to the panel. I use a LED headlamp AND a hand-held flashlight when I go wire hunting. You may have to nip off a wire tie from a wire bundle to physically follow the wire you're tracing back, you may pull on the wire to see the other end of it move a couple feet away, etc. It's all a part of the mission. Maybe it is a disconnected wire or something a P.O. changed from the factory. Who knows? The good news is you will find it, wire it up as it should be and you'll know a lot more about your boat! Good Luck!
