Replacement and maintenance
For accuracy, test battery voltage using a volt-ohm meter (customer supplied). When it is
time to replace the house batteries, replace with Group 27 deep cycle batteries only. Contact
the battery manufacturer for further information. Do not reverse the positive and negative
battery cables. Doing so will blow the reverse polarity fuses that protect the power converter.
Chassis Battery
Each chassis is built with batteries to provide energy to start the engine and operate devices
supplied with the chassis. The chassis battery is furnished and warranted by the chassis
manufacturer (as applicable).
AuxiliAry stArt systeM
Your motor home is equipped with an auxiliary start switch which can momentarily connect
both the house and chassis batteries should the chassis battery become discharged.
To operate, depress the “Aux. Start” switch (located on the front driver’s dash) and hold it
down. While the “Aux. Start” switch is depressed use the ignition key to start the chassis
engine. Release the “Aux. Start” switch after the engine has started.
Remove metal jewelry and always wear eye protection when working around
batteries.
Do not allow battery electrolyte (acid) to come into contact with skin, eyes,
fabric or painted surfaces. Electrolyte is a sulfuric acid solution that could
cause serious personal injury or property damage. If your hands, eyes, clothes
or the painted surface of your motor home are exposed to electrolyte, ush
the exposed area thoroughly with water. If electrolyte gets in your eyes,
immediately ush them thoroughly with water and get prompt medical
attention.
12-volt bAttery disconnect
The 12-volt battery disconnect switch is typically located
near the entrance door. This momentary switch controls a
latching type solenoid (located near the house batteries),
which connects or disconnects the house batteries
dependent upon the number of times it is pushed.
When engaged the battery disconnect solenoid supplies
battery power to all accessories connected to the house
12-volt fuse panel.
The battery disconnect feature should be used to disconnect
the motor home from house battery power during periods
of storage or during maintenance. The solenoid must be engaged for the 12-volt house
electrical system to operate. Never depress the momentary battery disconnect switch for
