Dear All,

I've searched these forums, and also Raymarine's website. Does anyone know if there is an off the shelf connector for two of these IMG_20170205_083628.jpg ?

If not I am going to have to take everything apart again to fit the new chartplotter

Thanks

Don't know of a purpose-made connector, but 3mm male spade connectors should fit in them. You could make up 3 wires each with spades on the ends.
Or cut them off and solder, or choc. block!
 
You have a few options.

Yes, there is an official junction block, into which you can plug up to three of these. Looks like a black rubber cuboid with three holes in one of the large faces, and a blanking plug on an attached strip for when you only have two plugs inserted. Perhaps no longer available new though.

The actual connectors in these plugs are a standard size of spade terminal. So you could make a joining piece out of six male spades (a forum search will find the proper size) and three short lengths of wire, plus appropriate physical packaging like a junction box or heatshrink. It's a bodge, but it should be reliable, and it leaves the original plugs intact if you need them one day.

If you don't expect to need the plugs again, you could cut them off and just join the cables. There's nothing special about them, just three cores to crimp or solder and then waterproof with adhesive-lined heatshrink. That's probably what I'd do if I didn't need the plugs for maintenance.

You could use a Raymarine 3-way junction box, part number D244, as shown on this page - http://www.raymarine.com/view/?id=5535&collectionid=26&col=5558

Heh - how much did Raymarine charge for a plastic box with their name on and a strip of chocolate-block? :p

I daresay a fortune. I got mine off ebay but I must admit I thought there was more too it when I bought it. It is a very pretty box though:)

PS. I used wago connectors instead and threw the chocolate away. Could have done similar with something much cheaper

But if you do decide to cut them off (which is what I would do) then cut off the plug with as long a piece of integrated cable as you can manage.

I bought such a Seatalk1 cable off eBay a few months ago with the plug on one end and bare wires on the other and paid £25.

You've got £50 burning a hole in your pocket right there! :)

You say its a bodge, but this year I found the Autopilot head on my HR had been installed that way by the factory (admittedly with some anti-corrosion grease). Its worked for 19 years without missing a beat.

Exactly the same on my boat .... which is why I bought the cable in post #10 .... so I could replace the three 2.8mm spade connectors with the pukka Raymarine plug.

That's why I also said it would be reliable :)

I think it's much more acceptable to use female spades into the back of the instrument heads - indeed for the transducer wires, that's the Raymarine official method and what I have on my boat. But two plugs joined back-to-back with spade-ended jumpers and stuffed into a box or bundled up in tape or heatshrink definitely counts as a bodge because it's bulky and inelegant - but not unreliable.

Thanks All,

In the end I just cut it and use a terminal block. I have a wheelhouse as well as an external steering position on my Nauticat so was fitting a secondary new A series chartplotter in the wheelhouse. In the end I used some insulated fittings for the positive, and negatives and a chocolate box connector for the yellow data wire. I bought the new conversion unit from Raymarine which converts the Raymarine 1 output to the up to date format so the new chartploter now outputs the values from the existing wind and depth sensors. All seemed to work very well when I tested it today.
