MANDALAY
The battery disconnect switches allow you to easily disconnect the coach and chassis
batteries from electrical circuits, preventing unwanted discharge during short periods of
non-use. For long periods of non-use: Walk through the RV and manually shut off all 12 Volt
powered items by their independent power switch. Then turn the coach and chassis disconnect
switches to the OFF position. The coach switch is mounted in an overhead cabinet above the
passenger seat. The chassis switch is located within the battery compartment.
There are three main uses for the battery disconnect switches:
1. Prevent unwanted discharge of batteries during extended periods of storage.
2. Prevent shorts or fire hazards while working on the 12 Volt electrical system.
3. Can help protect the batteries in the case of overcharging.
When activating, place the switch for the desired battery system in the ON position.
This battery system will now be operational.
The disconnect switches must be in the ON position while plugged into shoreline power to
charge the batteries.
Place the coach switch in the OFF position to disconnect 12 Volt circuits.
NOTE: It is not necessary or advisable to use the battery disconnect switches as a
substitute for turning off the various 12 Volt applications available in the motorhome.
NOTE: If 12 Volt functions are not working, be sure to check that the battery disconnect switch
has been placed in the ON position.
