Not the wiring plans that Fleetwood will send you, but the build/repair plans that are used to build the MH, and RV techs use for repair. Before just replacing the batteries, use a hygrometer to test the cells. Use a manual charger overnight, and test again after an hour of rest. If the hygrometer and a voltage test are good, a load test can be performed. If the batteries are good or replaced, you really need to find out what the hidden loads are, to prevent draining the batteries.
