catalina 22 mast power problem

On my 1987 Catalina 22, the mast lights weren't working. Possibly due to my voltmeter being so old and not working right, I got no reading at the deck plug. Because I had so much trouble trying to hook up a new one, I had the boatyard do it. Then the steaming light worked. They told me to change my bulbs, so I pulled down the mast and did that. No change. Now with a new voltmeter, I find that the deck plug connections for the anchor light and deck light are not powered. I have asked the boatyard to check their work, but it might not be the plug. I did notice in connecting the mast sid of the plug that when I stripped the wires they don't have bright copper inside, they are corroded. Probably true in the deck-side wires as well.

We have dreams of a week in the San Juans, we'll need our night lights to work.

I will check the switches at the panel, that might be the problem. But I might need to pull new wires.

Where do the wires go, to get from the panel to the mast? Is it a huge deal to pull new wires? I fear losing the end of the wire somewhere inside the boat where I can't get at it.

Re: catalina 22 mast power problem

The C22 owners association is a better place for a question this specific:


I belong to the C25 assoc, they pull my ass out of the fire all the time.

Good luck!

Re: catalina 22 mast power problem

Depending on the construction of the plug, you might be able to take it apart to try to determine if it is the plug or the wiring. (test for voltage on bare wires, and continuity thru the plug).

Re: catalina 22 mast power problem

Start at the battery and methodically work your way to the plug at the mast step, tracing each circuit with a continuity tester. Don't skip the switches or the fuses. If you have green, corroded wires, they probably should be replaced with tinned marine grade wires or at least cut back to shiny copper and dosed with dielectric grease. Once you get to the plug at the base of the mast, I would recommend making a jumper that is long enough to go from the mast base connector to the corresponding plug on the mast when the mast is down. That way, you can prove each light before you raise the stick. Be patient and thorough and you'll only have to do it once. If you must, make a temporary jumper to bypass any problem areas so you can take your cruise. A big flashlight is really all you need in a pinch with a 22 footer. If you need to cut away the overhead to get to the plug where it goes through the coach roof, do a neat job and make a neat patch so you can get to it again in the future. That fitting probably should be re-bedded from time-to-time anyway, so having easy access will encourage you to look after it.
