Section 6: Electrical System
71
The Electrical System
The RV electrical system is comprised of two independent electrical systems. One operates
off of 12-volt DC power and the other off of 120-volt 60hz AC power. All installations have
been made in compliance with industry standards applicable on the date of manufacture.
Because the electrical equipment and associated circuitry are engineered into a dedicated
system specific to your RV, do not make unauthorized changes or add fixed appliances to it.
Changes or additions made after delivery may result in a hazardous condition.
Service and/or modification of the electrical system should only be performed by qualified
electrical technicians using approved materials, components, and methods meeting current
safety and code requirements. Consult your dealer’s service department for assistance.
To read more about the various components incorporated into the RV electrical system,
please refer to the information contained in your Warranty Packet.
For motorized vehicles, consult the Chassis Guide for information pertaining to the chassis
drivetrain electrical system.
Electrical System Maintenance
Before working on the electrical system:
Make sure the inverter/charger (if so equipped) is turned “off” before disconnecting
batteries.Disconnect the shore power cord.
If equipped with a generator, turn off the generator and disable the automatic generator
start functionality (if so equipped).
Turn off the battery disconnect switch (if so equipped)
Turn off the 120V main circuit breaker.
Disconnect the negative 12VDC battery terminal from the battery.
Use caution when using metal tools. If a tool contacts a battery terminal or
metal connected to it, a short circuit could occur which could cause personal
injury, explosion or fire.
