[Tiara Open] 1996 3300 Open bilge float switch wiring

[hunter1897]

I totally get the wiring diagram and how it "should' be wired. But when testing the wiring there is no voltage coming from the auto wiring. The surveyor stated the float wasn't working either so obviously I'm trying to get a new float in there. And I want it to be powered from the opposite set of batteries as the manual switch...keeping things fail-safe. To track the wires back is nearly impossible because everything is withing looms. Kind of curious if my wiring has been updated from OE.
