Section 6: Electrical System

12-Volt DC System
The majority of your motorhome lighting is powered by 12-volt electricity. The 12-volt DC
system is composed of components that will operate when the following conditions are met:
Power is supplied by the chassis alternator when the chassis engine is running.
12-volt DC power is supplied when the shore power cord is plugged into a 120-
volt external power source. House batteries will be charged also in most situa-
tions.
The house batteries power many interior 12-volt components including the light-
ing fixtures, water pump, 12-volt motors, 12-volt appliances, etc, when the mo
-
torhome is not connected to a 120-volt power source.
12-Volt Fuse Panel
The 12-volt fuse panel is labeled to indicate fuse sizes, positions and the components pow-
ered. Fuses are located in the load center.
Replacing a Fuse
Before replacing a fuse, always turn off the electrical components protected by it.
1. Disconnect the shore power cord.
2. Inverter should be OFF.
3. Remove the fuse panel cover to check fuses.
4. Pull the fuse straight out of the fuse block.
5.
Insert a new fuse of the same specified voltage, amperage rating and type in the original
location.
The fuse panel label should be kept permanently affixed to your recreation vehicle. Fuses
will not offer complete protection of the electrical system in the event of a power surge or
spike.
Replacement fuses must be of the same voltage, amperage rating and type.
Never use a higher rated replacement fuse
; doing so may cause a fire by
overheating the RV wiring.
Pressing the SELECT button also cycles through in-
verter settings. Inverter settings can be changed, but
12VDC must be removed from the Ignition Start Port
on the back of the inverter. Unplug the 12VDC wire(s)
on the back of the inverter to make changes to invert-
er settings. Plug +12VDC back in after settings are
changed. (See photo)
Refer to the Inverter manufacturers’ manual in your
warranty packet for further operating instructions, er-
ror codes, changing inverter settings and safety infor-
mation.

NOTE:
The power button is
NOT
a power disconnect switch and will
not remove DC power from the inverter. Disconnect
ALL
power from the
inverter before working on it.
