Breaker Boxes; Batteries; Battery Boost Switch - NewMar Scottsdale Class A 2006 Owner's Manual

Breaker Boxes

The 120 volt and 12 volt breaker boxes are generally located in the overhead
cabinet on the rear bedroom wall. Circuit breakers and fuses are installed to
protect the electrical system from overloading. Do not attempt to change the
circuitry or add appliances yourself. Please consult an authorized Newmar
Service Center.

Batteries

The chassis batteries on your motorhome are installed and warranted by the
chassis manufacturer. The four 6 volt coach (or house) batteries on your
motorhome are installed by Newmar Corporation, but warranted by the battery
manufacturer. These batteries are used to operate the 12 volt items that are not
a direct part of the chassis. They are located on a pull out tray in an outside
compartment.
CAUTION
Do not use the motorhome with the coach batteries disconnected.
The coach and chassis batteries are recharged by the vehicle's electrical system
whenever the engine is running. A decline in the coach battery voltage may be
noticed while the chassis batteries are being charged. The converter will
automatically charge the coach batteries when the unit is connected to a 120
volt outside power source. The chassis batteries are isolated from the coach
batteries. This prevents the chassis batteries from being drained by the interior
12 volt equipment, allowing ample voltage for engine ignition.

Battery Boost Switch

The battery boost switch is located on the dash. This switch briefly connects
the coach batteries to the chassis batteries. This allows the chassis batteries to
borrow power from the coach batteries to assist in starting the engine. If the
chassis batteries cannot turn the engine over in the normal mode, hold down
the battery boost switch and attempt ignition. By using the battery boost switch
while trying to start the chassis engine, a jump start situation is created
between the coach and chassis batteries. If the battery boost switch is required
to start the engine on a regular basis, ask your dealer to check the chassis
batteries and charging system.
