Folks,

I crushed my mast light connector when we raised the mast last week.
Hence, I don't have the wires pinned out for the connector for the deck connector.
I have a deck light, steaming light (aquasignal mark 25 combo) + an anchor light.

One of the wires is a common ground.

The colors are

Red
White
Green
Black

I can probably deduce this with some time and VOM, but if anyone knows the correct sequence I would prefer to start off on the right foot.

Thanks,

Hi Sam,

Here is a link to the lighting wiring schematic ... it should help answer your question: [url="http://www.catalina25-250.org/manbro/pictures/owners11.gif"]Lighting Wiring Schematic[/url]

'Sounds like you and I have the same luck!

Good luck ... 'hope you get it all back together and working OK.

On my 1983 the male plug/pin colors are as follows:
White - Ground
Black - Steaming Light (Bow Light)
Green - Anchor Light at masthead
Red - Deck Light

This is different than the Owner's manual for wire colors leaving the switch/fuse panel. Given the shoddy splicing inside the base of the mast, it might have been rewired by a PO.
A 9-volt battery is a handy way to check which wire color/pin is to which light.
Good luck.

That 9 volt sounds useful. My anchor light is out, and I am trying to narrow down the problem. So I can take the 9 volt battery and connect it to the connects at the bottom of the mast? Is that how it works? I hope I am not stating the obvious!!

The 9-volt battery's ground (one side is marked with "+", the other is the ground) is connected to the ground pin (the big one on my boat) of the male plug that goes into the deck fitting from the mast. The other lead is connected to one of the two or three other pins in the male plug to dimly illuminate (hopefully) the various lights on the mast. If it sparks, there is likely a shorted wire and you have more problems. I robbed the 9-volt contacts from a defunct smoke alarm to make fittings for the battery, but you could probably use aligator clips. The female "bullet" removable connector in 14/16 gauge (the blue ones) can be used to fit the ground pin and the male can be spread open just a tad to fit over the other pins. I'd be happy to email you a picture.
If your lights work with the 9-volt battery on the male plug, and you have used a 12-volt checker to verify voltage at the female deck fitting, the the problem is corrosion on the male pins or female holes. The male plug can be disassembled (remember how it goes back together write down and which color wire goes to which pin - or you'll have to trace it out later) and the pins cleaned up with 320 grit emory cloth. Or at first, you can try cleaning them up without dissassembling. The female holes can be cleaned by rolling small 1" square pieces of emory cloth into a size that will fit down the female hole in the deck fitting and then twisting.
My anchor light tested okay with the 9-volt battery, and there was voltage at the female plug, but it wouldn't work when plugged into the deck fitting. Cleaned out the female contact and it worked fine.
Hope this helps.
Best regards,
