What is the "accessory" breaker supposed to control on the main breaker panel of my 88 340 Express Cruiser? Mine doesn't seem to do anything. Thanks

Maybe it does not do anything. Those were often there for dealer added options as was more common in 88. You may not have an option that needed it.

Thats what I was thinking. I guess I could pop the panel off quick and see if its got anything wired to it. Thanks

Mine is hooked up to the power side of the digital tv antenna.

Check any outlets that may only work with it on also.

On my ‘88 340 Sundancer, the Acc switch at the helm powers the bilge lights and the depth finder. I doubt that was how it came from the factory though as those two things don’t make much sense wired to the same switch. On the 120 volt panel, acc isn’t connected to anything.
