E. THE ELECTRICAL SYSTEM

Most electrical devices in the motorhome run on 12 volt DC current: lights, fans,

water pump, etc. In addition to these, there are some other appliances that can

only be used with 110-volt alternating current. The roof air conditioner requires

110V AC, as does the microwave. The refrigerator, when used on the electrical

setting, requires 110V AC – it will not run on 12V DC (of course, it can also be

used on the LPG setting). You get 12V DC from the auxiliary battery (see section

on auxiliary battery).

You must be connected with an external source of electricity or be running the

generator to get 110V AC. To hook-up at an electrical source, pull the electrical

hookup cable out of the side compartment on the left side of the vehicle and

connect it to an outlet. It is possible that the plug will not fit and that you will need

to use the provided adapter.

1. 12-volt, 110-volt: All motorhomes have two separate electrical systems: a 12-

volt DC system (from a battery source) and a 110-volt AC system (from the

generator or from an external power outlet. The engine battery is charged by

the alternator while driving the motorhome or while the engine is idling. The

engine battery runs chassis-related functions, while the auxiliary battery runs

cabin-related functions. Please note: the auxiliary battery will not run the

house A/C, the microwave or the 110 volt outlets without either being plugged

in to shore power or without running the generator.

The auxiliary battery is charged in two ways: (1) by being plugged into an

external power source, or (2) by the engine alternator while driving the

motorhome or while idling. The preferred, and faster way of charging the

battery is by running the engine.

Chassis: The chassis has a set of fuses and circuit breakers that are separate

from the coach and run independent components on the engine, dash and

exterior lights. If electrical components are not working, a fuse may have

blown. The fuse panel is located below and to the left of the steering wheel by

the brake pedal. Blown fuses are

identified by a broken wire within the

fuse. Check the appropriate fuses

before replacing any electrical

components. Note: ALWAYS

replace a fuse with one that has the

SAME amperage rating. Using a

fuse with a higher amperage rating can cause severe wire damage and could

start a fire. Please call Roadside Assistance if you suspect a problem with a

fuse.

Because fuses change in color and placement from year to year, please call

Roadside Assistance and refer to the fuse cover for the correct fuse amperage

and position.
