Checking for Blown Fuses
If a 12V DC device or wiring fails in such a way as to create a short circuit, the fuse for that device will
blow. Each fuse has a metal strip inside that is designed to burn out if too much current flows through
the fuse.
If a 12V DC device is not working, check the fuse that protects that circuit. If the metal strip inside the
fuse is obviously burned out, replace the fuse. If the fuse looks ok, don’t rely on the visual check. Test
the fuse with an ohm meter.
If the new fuse blows immediately when you try to use the device on that circuit, further investigation
will be required to determine why the fuses are blowing. If you aren’t sure how to investigate, you’ll
want to contact your dealer or a qualified service shop.
Batteries
Because the Landmark 365 ships with a residential refrigerator, it also comes with two 12 volt batteries,
wired in parallel. Wiring in parallel keeps the voltage at 12V DC while increasing the length of time the
batteries can supply power. When not plugged into shore power, the batteries supply power to all 12V
lights and other 12V devices. This includes circuit boards on the water heater, furnace, the auto-leveling
system and hydraulic pump, motors for electric slide outs, the Power Control System, and 12V lighting.
Battery Cutoff Switches
There is one battery cutoff switch for general 12V operation, and a second one for the residential
refrigerator power system. Cutoff switches are located in the front compartment.
