Replacement And Maintenance; Battery Disconnect Switch; Rotating Dial Disconnect Switch - Jayco 2016 White Hawk Owner's Manual

SECTION 6 – ELECTRICAL SYSTEM
A fully charged auxiliary battery will read 12.7 volts DC and 1.265 specific gravity at 80°F
(32°C). The auxiliary battery is considered discharged at 11.8 volts, and dead at 11.65
volts.
When voltage drops below those levels, permanent damage may occur. Typically, a deep
cycle battery has an amp-hour rating of 75-100 amps.
If you run the furnace and refrigerator simultaneously, you will be using approximately
(12.0 + 3.0) 15.0 amps per hour. This does not include any 12-volt lights, water pump or
any other 12-volt component.
If the furnace and refrigerator in the above example operated constantly, a 75
amp-hour battery would become fully discharged in 5 hours
5h).
The auxiliary battery should be installed in parallel with the battery in your tow vehicle.
When the 7-way trailer plug is connected, both batteries power the RV so it is important
not to discharge your tow vehicle battery below the level required to start the engine. To
prevent this from occurring, disconnect the 7-way trailer plug or install a battery isolator.
When the tow vehicle engine is operating with the RV connected, the tow vehicle charging
system will charge both batteries.

Replacement and maintenance

Some equipment in your RV will draw small amounts of current even when turned OFF.
To prevent the auxiliary battery from being discharged when your RV is not connected to
shore line power, disconnect the auxiliary battery negative cable at the battery. During
storage, it is important to check the voltage monthly and recharge the auxiliary battery as
needed. If you remove the auxiliary battery from your RV, store it in a dry, cool area per
the manufacturer's instructions.
When it is time to replace the auxiliary battery, replace it with a Group 27 deep cycle
battery only. Contact the battery manufacturer for further information. Do not reverse the
positive and negative battery cables (doing so will blow the reverse polarity fuse(s) that
protect the converter).

ATTERY ISCONNECT
The Battery Disconnect switch is located in an
enclosed exterior compartment typically at the front
of the recreation vehicle. Depending on your model
RV, it will have one of two styles of disconnect
switches. Contrary to its name, the Battery
Disconnect does not switch off all power to the
batteries or the entire RV. The switch only shuts
off the 12VDC power to the main 12V fuse panel,
and the interior of the vehicle. Batteries can still be
trickle charged by the converter, and there will still
be power to the landing legs on Fifth wheels and
certain other devices.

Rotating Dial Disconnect Switch

When this switch is ON, there will be a green area
visible along with a "1" (one) at the top of the
switch. To turn the switch OFF, turn it counter-
clockwise until you see red area along the left side
of the switch showing a "0" (zero).
