SeaMaster 24 wiring

[Antony Collis]

Can anyone help with some wiring on a seamaster 24.
There is an original loom behind the helm that runs up to the top of the bulkhead and goes through the wall into the ceiling. It has 4 green earth wires a purple, a yellow and a smaller blue. The yellow and purple are the positive for the roof lights but does any one know what the blue would be for. I can't find the other end and cant take the ceiling down.

Thank you.

Could it go out through the roof for nav lights, hooter or search light?

The cable is smaller than that used for the interior lights but then again they seem to have quite thick cable. There is no obvious hole through the hull anywhere for anything external but they may have been filled previously. im refitting the boat for someone and just wondered if i could use the cable if i knew where it went.

It would have had nav lights when new so I would guess they are for those, have you tried the owners club?

I have found that the yellow wire does the port cabin light direct. The purple is the stbd cabin light but through a switch just inside the door and the blue is for the toilet light.
thankyou
