For the last two days I have been pouring over the schematics from Ford and Winnebago to find the source of the power to the Aux. Battery switch and to day I decided that no more reading and today it would be fixed.
I checked every fuse and relay that was hot when running, all were in good shape. Then I poked and prodded the humongous mess of wire under the dash pod, in doing so I learned to tell at a glance which looms were Ford and Which were Winnebago. The schematic from the Winnie installed switches and accessories. Winnie's schematic showed a connector near the floor on the left side of the steering column. I tried and tried to find the wire Winnie said carried load when the engine was running all to no avail, until! I realized that the connector to the immediate left of the steering column was a Ford loom and not Winnebago. In addition it was through the firewall and not the floor.
I found the circuit and it was hot with the key on, just as it is supposed to be. But at the first place back into the spaghetti of wires that it was accessible, it was dead.
The wiring is so inaccessible I just ran an additional wire from the connector on the floor to the wire that provided the Hot When Running power and spliced it in.
Success, the batteries both charge when the engine is running and all of the other accessories are also working.
Tomorrow is tax day and Best Buy for some info on using cell phone when I have WiFi but not cell signal, Thursday will be climb on the roof and measure the Neo-Shape skylight and order the new skylight exterior dome and 50' of EZE Gutter for over the windshield and side windows.
It should all be here in time for installation before our next trip the end of the month.
