My bow navlights don't function and I can't find the problem. Bulb is ok, but there seems not to go any voltage through the wires.They appeared somewhat corroded, so I cleaned them, but to no avail. The stern navlight works, as do the mast lights, so I suppose the problem would be between where the wiring for the bow navlights is connected to the main nav lights circuit and the bulb. Seems a rather nasty problem, because it looks like I'll have to take out the stanchion to get there. Or is there a fuse that could have blown, but where would that be? The wiring diagram in the owners manual doesn't show any fuses. If anyone could point me in the right direction, I would be grateful. Still on a steep learning curve re electrics.......

Bow Navigation Lights Out

Edward, I suddenly ran into the same problem this past spring. The electrical wiring to these lights runs within the deck core on my '77 C30. I have a couple of longer 14 guage wires with aligator clips at each end. I knew that my port cabin light in the V-berth worked so I dropped it and hooked onto the wiring in it with these "jumper wires". I found I had POS power to the bow nav lights but no NEG. So I ran a new wire from the Neg side of the V-berth cabin light over to the port side of the hull deck seam and hid it behind the vinyl beading up into the chain locker. The nav light swith on the panel works as normal as I only connected/extended a ground wire. Cliff Carter C-30 #598 Oak Bay, B.C.

Bow Nav Lights

Edward: Last summer, after I purchased my 1986 C30, I also learned that the bow nav lights were not functioning. I went into the anchor locker and traced a splice that had simply come undone due to corrosion at the splice. Good luck, Mike

Check wiring behind ash panel above closet

If I remember correctly, the bow light wires run along the starboard side (just inboard of the hull-to-deck joint and may be painted over) from the nav-station electrical panel, all the way to the bow area, and then as mentioned, there are connectors, which might be visible if you lift the forward v-berth plywood cover (the little one) and stick you head/mirror in and look upward. You should also be able to see the wires in the v-berth if you look up behind the teak trim in the V-Berth. However, the wires in my 1988 were rather tight, and the hull flex caused them to rub/wear/short on the stanchion base nut which is behind the ash panel above the closet. So, if it is not the connectors in the v-berth, try looking behind the ash panel. It can be removed by first removing the screws in the dark teak upper trim piece, then the electric outlet cover, then the screws on the sides holding the ash panel in place, and then gently wiggle it out and look behind at the wires. By the way, while your in there, be sure to tighten the stanchion's nut (they loosen-up over time -- also that is the stanchion which has the vent hose for the bow and starboard water tanks, so also check the hose clamp and inspect the hose too). Hope this helps..

hull 593

Cliff. Hello. I noted that your hull number for your Cat 30 is 598. Ours is 593, so we are close Cat 30 relatives here in the USA. I have seen Hull # 595 here in Erie also. Yep, wiring is fun. I still havent found the mast wiring for my Masthead and steaming lights. I know the connectors are at the mast step, but apparently They are either corroded or not connectd by the PD. In the Spring I will pull the mast and find out. Regards John
