Chassis Batteries; Isolator Solenoid - Jayco 2016 ALANTE User Manual

JAYCO CLASS A MOTOR HOMES
Battery storage instructions
Some equipment in your motor home will draw small amounts of electrical current
even when turned "off". To prevent house battery discharge when the motor home
is not connected to power through the shore power cord, it is recommended you
shut "off" the 12-volt battery disconnect solenoid and disconnect the battery
negative cable at the house batteries.
During storage, it is important to check battery voltage at least every two weeks
and to recharge them as needed. If you remove the batteries from your motor
home protect them from accidental shorting and keep them in a cool, dry, well
ventilated area.
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.

HASSIS ATTERIES
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).

SOLATOR OLENOID
When house batteries are installed in parallel circuitry with the chassis battery, the
charge level in both connected batteries will naturally equalize. An isolator
solenoid is incorporated to break the connection between the house batteries and
the chassis battery when the ignition key is in the "off" position.
Breaking this connection prevents discharge of the chassis battery (used to start
the engine) when using 12-volt devices in the house section of your motor home.
When the engine is running the isolator solenoid engages allowing the house
batteries to be charged by the vehicle alternator.
Always leave the ignition key in the "off" position unless the engine is running

VOLT USE
The 12-volt fuse panel is labeled to indicate fuse sizes, positions and the
components powered. At the beginning of camping season, inspect all the 12-volt
fuses and replace as needed.
Replacing a fuse
Before replacing a fuse, always turn off the electrical components protected by it.
1. Disconnect the shore power cord.
2. Turn "off" the inverter (if so equipped).
3. Disconnect the house batteries main negative battery cable.
4. Remove the fuse panel cover to check fuses.
5. Pull the fuse straight out of the fuse block. If the fuse is not blown, something
else must be causing the problem. Please contact your dealer for further
assistance.
