ELECTRICAL
Power Sources
The 12 Volt Electrical System allows certain components
to maintain a low voltage from the battery bank. The
battery bank is controlled by the coach charging
system, which consists of a charge bridge solenoid, a
bi-directional isolator relay delay (BIRD), or a battery
isolation manager (BIM). When the coach engine is
running, the alternator charges the chassis batteries and
may assist in charging the house batteries through the
BIM, BIRD, or Charge Bridge.
When the coach is connected to shore power or when
the coach generator is in use (when shore power
is unavailable), the converter or inverter/converter
combination recharges the house batteries, and with the
assistance of a BIM, BIRD, or Charge Bridge, it can also
charge the chassis batteries.
In addition to the alternator
and converter, the coach
may also be equipped with
solar panels to provide an
additional option for charging
your house batteries.
ALTERNATOR
The alternator is a belt-driven component attached
to the coach engine and is supplied by the chassis
manufacturer. The alternator supplies power for chassis
components such as batteries, lights, wipers, dash HVAC,
and power seats, as well as all of the driver controls
located in the cockpit. The alternator charges the chassis
batteries, but with the addition of a BIM, BIRD, or Charge
Bridge, it may also assist in charging the coach’s house
batteries.
ELECTRICAL
Due to the risk of electrical shock, service should be performed by a qualified electrican or authorized service
technician. The electrical system may have multiple 120/240 volt power sources. All power sources must be turned
off, and any auto generator start features must be disabled prior to servicing.
WARNING
!
12 Volt Electrical System
This article provides general information about the components and functions of the 12 Volt Electrical
System (DC) in Newmar coaches.
This chapter includes overviews of the 12 volt and 120 volt electrical systems, as well as information
about electrical equipment that may be installed in your coach, including, but not limited to fuse panels,
lighting, EMS, generators, inverters, converters, solar panels, transfer switches, etc.
Any of the following quick start instructions provided by Newmar should not take the place of the manufacturer’s
complete documentation. Refer to Newgle for more information about electrical components offered for your
coach’s model year.
IMPORTANT
!
GENERATOR
When shore power is unavailable, the generator takes
mechanical energy and converts it into alternating
current to supply 120 volts to the coach and charge the
coach’s house via the converter or inverter/converter and
the chassis batteries via BIRD, BIM, or charge bridge.
The generator is typically located in the front of the unit
between the frame rails on diesel coaches. On gas units,
the generator may be located anywhere between the
mid and rear section of the coach. Generators can be
powered by gas, liquid propane, or diesel fuel.
CONVERTER AND INVERTER/
CONVERTER COMBINATION
All Newmar coaches are equipped with a converter or
inverter/converter combination. A converter transforms
alternating current or shore line power 120 Volts to low-
voltage direct current to provide power to the coach’s 12
Volt house and chassis batteries. On the other hand, an
inverter transforms direct current to alternating current to
provide power to specified appliances and entertainment
systems.
SOLAR PANEL
Some Newmar units are equipped with a 10 Watt solar
panel wired to the chassis batteries. Prior models may
have a five or 10 Watt solar panel and may be wired to
the chassis-side KIB panel.
