Taking pictures of certain junctions and the panels where the wires begin and end will be frustrating to say the least. Most of the time the wiring systems are color coded. There are schematics that are line drawings of electricial systems for nearly everything electricial. With a boat being as simple as they are when it comes to systems, I would do a drawing (if I didn’t have a factory schematic), of each electricial item in the boat and draw a line with colored pencil to and or from it taking the shortest path possible. Electricial wiring has many factors involved in its application . For instance, amount of current, length and gauge all matter big time. There should be a schematic out there somewhere as these Allmand boats are well documented . This is why electricians, especially nautical electricians make big money. Good luck and Great boat!!!
Have the factory Manuel schematic.prior owners just added and subtracted at will. Trouble with
