I recently purchased a '79 Catalina 25. The PO had damaged and 'repaired' the mast light plug. The wires were fitted with push type connectors and they were pushed over the exposed wire ends in the receptacle, and then caulked over. The leads that were left were so short and more damage occured when I was removing the caulk, and I think FG resin was involved in the repair also. Now I need to pull more wire through or create a splice to connect the new part when I get it. What's the easiest way to get to the wires inside the cabin?
You are facing the same problem I had with my '79 C-25 when I bought her in '96 - the wiring was bad and half the lights didn't work. The bottom line is that the Catalina factory did not use marine grade wire in these boats back them, and did not leave any "extra" length you could pull out. Also, the wires to the mast wiring socket/deck plug are embedded into the fiberglass between the outer and inner cabin top moldings, and there is really no good way to get at them without involving major surgery and repair. Most owners in this situation end up installing complete new wiring between the batteries, switch panel, and whichever light fixtures are non-functional. You will not be able to route the wiring the same way the factory did, of course, so you will run your new wiring under the settees and through the bilge space if necessary. Highly recommend you use 100% tinned An-Cor marine grade wire, even though it is more expensive than non-tinned wire, as it will resist corrosion for many years, and you should not ever have to do the job again, at least for as long as you are likely to own the boat. Re-wiring a boat is an exhausting job, and you don't EVER want to have to do it again!
I rewired my mast lights last year, and ran four-ply wire above the port saloon shelf, through the bulkhead, and up to the hole through the deck to the mast plug. Use cable ties to attach the wires to the bulkhead.
Larry is correct in using Ancor wire. You don't want to have to do this again. When I rewired my boat I used 14-5 wire on the mast. This let me power up the anchor, steaming, deck, and windex lights. Aqua signal makes a great 5 pin connector. I just ran the wire along the surface of the cabin roof. I didn't even try to run it inside the deck.
Can't I just tie the old wire to the new and pull the wire through?
