Fuses & Circuits; Rear Start Switches - Holiday Rambler Imperial 2008 Owner's Manual

FUSES & CIRCUITS
The motorhome relies on two electrical panels
to control chassis system functions and some
house operated items. One electrical panel, located
roadside ahead of the front wheel, contains fuses,
self-resetting circuit breakers and micro-relays.
The other electrical panel, located in the engine
compartment, contains high-amperage circuit
breakers, a high-amperage solenoid and the rear
start box. The circuit cards in both electrical panels
use LEDs to indicate power.
RED indicates Fuse.
GREEN indicates Relay.
YELLOW indicates Signal.
Front Electrical Bay: Located in roadside front bay.
Rear Run Box: Located in engine compartment.
The fuses are standard ATC blade type. When
a fuse blows, generally the wire in middle of
the plastic case will be broken. A bad or blown
fuse must be replaced with a fuse of the same
rating and type. Using a fuse of a different
type or rating will defeat the circuit protection
provided by the fuse and result in damage to the
motorhome electrical system.
A fuse that has been replaced and continues to
blow may indicate a fault exists or an electronic
component has failed. It is recommended that
the motorhome be taken to a qualifi ed RV
technician before any future use to diagnose
and repair the potential problem. Circuits are
identifi ed with a label adjacent to the fuse.

The FRONT/REAR switch has three positions:
1. FRONT - In this position the
motorhome will only start with the
ignition key.
2. OFF - In this position
the starter will not
engage with either
ignition key or rear
start switch. It will also
turn the engine off if it
is already running.
3. REAR - In this position
the motorhome can
only be started with the
rear start switch. (Note
that the ignition switch
must also be in the ON
position.)
The START switch engages the starter when
the FRONT/REAR switch is set to REAR and
the ignition switch is ON.
CAUTION:
When checking or servicing the engine
compartment, the Rear Start switch
should be placed in REAR or OFF
position to prevent accidental starting of
the engine from the cockpit area.
NOTE:
If the motorhome will not start from the
front, check the rear start box to see if
the switch was bumped or accidentally
set to OFF or REAR. If the ignition still
does not engage, try to start it from the
rear start box.
