Purchased a cessna style master/split switch from A/C Spruce in order to eliminate toggle type switches for isolating the battery in the event of an alternator failure. Problem is that it did not come with any wiring diagram or have any of the tabs on the back of the swich marked. AeroElectic schematic Z-11 shows using it but it is not the same style switch that I received from A/C Spruce. Has anyone out there used this type switch and if so do you have the wiring diagram denoting which tabs go to what? I realize that 3 tabs are for the alternator side and 3 for the battery side but 2 are doubled tabs on each one but not layed out the same, ie battery side has double top single bottom and alternator side has single top and double tab bottom. thanks in advance.
