wiring diagram for mast lights and bow lights

[dknape]

My current problem is that when my mast was put back up, my mast lights and bow light no longer function on my 1987 Hunter 26.5 sailboat.

The wiring is likely all original and and thus not tinned. The wiring also has a lot of black electrical tape above the deck. The stern light does function. The forward cabin light also does not function. Tried moving the light bulbs around, the same light continued to not function.

I am looking for a wiring diagram to assist me in fixing my wiring problem.

Thank you in advance for any help and or suggestions you can provide me.

it should be a fairly simple task..... without a schematic, if you know what a continuity tester is and how to use it. but you also need a regular test light also.
if it happened when the mast was either taken down or put back up, it could be a pinched wire or a broken ground. I dont know if the masthead light and bow lights have independent grounds or if they have a shared ground wire.
you need to find out if the ground wire at the light has continuity to the negative post on the battery, and the positive wire at the light needs continuity to the positive post on the battery.
find out which one has failed you and 2/3 of your work is done..... then you only need to find out where the failure is in that one particular wire.
is there any thing common between the two lights other than the battery?.... do they share the same switch?.... the same ground wire? the same hot wire?
with these ideas you should be able to locate the problem fairly quickly.....

I am having the same issue. My issue is where / how the wires run. How do you feed them through the ceiling / where do they go?? I've got a 78' H25.

The Red & Grn Bow lights and Stern light should all be on the same switch at the panel. Marked either "Running Lights" or "Nav Lights", or similar. The Steaming Light and the Anchor light should each have separate switches at the DC distributional panel. To do the continuity tests that Centerline talked about above, make sure all of the Nave lights, Steaming lights, and Anchor light are in the on position. Check them out one leg at a time. On my H-33.5 (1990) the Bow lights wires run along the Port side behind the settee. Im not sure where the Stern light wires run - probably start out on the Port side (that is the side that my DC distribution panel is), but cross over somewhere to the Starboard side where the Stern light is. The Steaming light and Anchoe light wires start out on the Port side and go to the top of the compression post and thru the deck to the base of the mast. There there are connections to the wires in the mast to the Steaming and Anchor , and Spreader lights. I hope some of this makes sense and is somewhat useful to you for your H-26.5. Good luck.

Another thought. There should be basic rudimentary schematics in the boats manual from Hunter. They should also be available on line from Hunter. Give that a try.

There are the basic drawings of the wiring, I'm wondering if anyone has fed new wire through the ceiling and how it was done.

As I've been working piece by piece on rebuiliding my salvage H22 for the past 4 years, I did not try to feed the wires through the salon ceiling, but just replace the wiring that I could access (splicing, taping over / heat shrink tubing at the connection points) and would make my own runs of wiring via accessible paths, and hiding / reinforcing with spiral wound cable protector as needed.

I am embarrased to admit it, but the issue with the bow nav light had nothing to do with the electrical. It was a bad bulb. Evidently, the bulb just simply went bad during transport from the Chesapeake down to South Carolina. I replaced the bulb and the front lens and all is now good with that light.

Now it is time for me to find my harness and send my wife up the mast to replace the bulbs on the mast and see if that might fix those lights too. I guess it is always possible that they were simply damaged during transport.

I have traced the red/blue wires coming down the mast to the thru-deck connector where they splice into a set of red/green wires below deck and back to the electrical panel under the companion way.
