1978 Gibson Fuse panel Question

[Billycollett]

I have a 1978 Gibson houseboat both roof top air conditioner have been removed in the fuse panel both switches are off. Is this the only thing these switches go to. Do they possibly go to the stove it does not work. Thanks for any help I’m planning to run new air conditioners off the breakers if that all that’s in them.

Didn't ever see a Gibson with roof top AC. My guess is the prior owner added them so no telling how it was done. With most all boats, each manufacture designs things somewhat different. Most have no wiring diagrams available to see, so we are all on our own.

Need to start tracing wires, and would start at the breaker panels
