No cabin lights

[john26]

Hi,
I have a 26 ft 1966 flybridge.I have never seen another one like her.Everything works except my cabin lights have no power.I have no blown fuses and can not for the life of me find where the line originates.A wiring diagram would be great or a tip on where the cabin light main feed comes in from.I hate to drop the ceiling panels. I really need a diagram..
Thanks for any help you can give
John

Good advise by Carl. Also check for corrosion on fuse block. I use a wire tracer kit sometimes to trace wires.
As far as I know no one has any Factory wiring diagrams.
good luck

Cool. Can you post pictures of your 26' flybridge?

Thanks to all for your input.I need to take a low res. pic of the boat , but I just cant get it to a small enough file.I have checked all fuses and its a very primitive system.I have no breaker/fuse box etc. area, one 50a fuse on the engine bulkhead and only a couple of fuses behind the upper and lower helm for blower ,bilge,lights.I have been around boats and old cars my whole life and am pretty fluid with electrical/mechanical environments.The fixtures all have yellow and white wires. I will get some pics up soon of wiring and boat.It seems very rare of a craft..Thanks for helping out guys.This is like pre standardized wiring.
A/C and D/C circuits using white and black randomly.

Thanks
John

Sending a tone down the wire did the trick.Cabin lights unmarket fuse upper helm yellow wire to black buss bar.Corroded,did a quick fuse spin and cabin lit up.Wife happy.
Thanks to all.Now onto why my white wires are being use as DC ground and black positive DC....LOL
