“ The auto side of the switch on the panel isn’t even connected to anything other than its own LED.”
This type of information if accurate is evidence of a willful sort of ambivalence to a technicians or hands on thinker boat owners sanity.If it’s true for my boat too, it led me to the incorrect assumption that my boat wouldn’t have an automatic bilge pump at the ready if I opened the house bank positive switch. I have stared at the bilge section with the pump and float about 10 times now, I had a habit of looking at bilges upon arrival and departure on my old boat, I know I can’t assume those floats always work, I’ve seen them fail. Ruined the cabin sole carpet on my old boat once. The bilges are bone dry every time I have checked on Marie Katherine. Still, given the choice of running down and cheesing $1,000 or so worth of batteries and driving 4 hours away from my boat with no automatic bilge pump at the ready, I would choose risking the batteries every time.
It cost Beneteau money too to make that bilge pump panel switch look and perform as if it was the way the automatic float bilge pump gets energized , if you’ve got a 3 position push button switch, with extra little lights at the bottom with symbols indicating auto and manual which I think it does, why not have the people designing, buying and installing that stuff talk to the people who are designing, buying and installing the wiring that powers the hot side of the float switch when battery isolator switch is open (and gives no indication that’s wired like that with a light or label)? Why have it just be a sort of rumor that it’s wired like that until one searches through the long book for the answer or wiring diagram that shows it? I have worked for manufacturers field service depts my whole shoreside career, and I’ve learned that unless someone makes a mistake, there’s nothing that cost the manufacturer time and material to put on their products that’s useless in actual operation, like you say the lit, auto pos bilge pump portion of the switch is. On large ships, if a shipyard put a switch on the bulkhead with lights and labels saying it’s the indication that a bilge pump will come on automatically when the ship takes on seawater, but it wasn’t wired to any float at all, I know some (now retired) chief and port engineers who likely wouldn’t bring their ship back to that yard- sounds almost criminal.
alas, now I’ll climb off the ledge.
