Help! Stuck in Arkansas

Hello everyone who responded to my distress signal. We needed each of your responses but could not get back to anyone since we had no wifi and only limited phone service. I told the repairman to call Fleetwood and ask them if they could send us a replacement or recommend one. Fleetwood said they had only one left in the entire U.S.A. and sent it to us. It was six days of misery as the weather was hot as H#$^. We had one extension cord for all our electrical needs and dirty well water. Now we know what dry camping means. D.E., thank you for responding with a private message, it was appreciated. I would very much like to have those schematics. I took pictures of the switch and how it was wired for any future problems it could pose. We don't ever want to be in that situation again. Thanks again everyone, we are back on the road again.
