There are also some circuits that are protected with an inline fuse. Some fuse blocks have fixed relays integrated on a
board. The board below is located in the cord compartment.
Basic 12 Volt Power Flow
Since a battery is only an electrical storage component, 120 Volt power
must be present to charge the batteries from the
converter or inverter/ converter combination unit.
It is necessary to have
12 Volt
power supplied from the coach's house
battery bank in order
to operate the interior lights and other 12 Volt
loads such as Slideout control systems, water
pumps,
vent fans, monitoring systems, etc.
Most of this power
flows through the battery disconnect to the fuse block or
mini-
breakers, which prevents overloading the circuit prior to progressing
to the 12 Volt
load.
There are some 12
Volt
circuits that do not go through the house battery disconnect; however, these loads still pass
through a fuse or mini-
breaker before progressing
to the load.
When a 12 Volt load or component is not working, both 12 Volt power (+) and 12 Volt ground (-) are needed for
the load to complete the 12 Volt circuit.
