ELECTRICAL
CHARGE BRIDGE SOLENOID
All current model New Aire,
Supreme Aire, Mountain Aire,
London Aire, Essex, and King
Aire coaches use Silverleaf,
a computerized coach
management system.
One of its many functions is to
control the battery charging
through the Charge Bridge Solenoid. The TM102 module
monitors the battery state and senses the house and
chassis battery voltage. When the parameters are met,
the TM102 module activates the solenoid, causing it to
bridge or connect the chassis and house battery banks.
For more information on your coach’s TM102 module,
refer to the SilverLeaf Functional Guide in Newgle.
To learn more, visit the Battery Disconnect home page in
Newgle.
BI-DIRECTIONAL ISOLATOR RELAY
DELAY (BIRD)
Current gas coaches and some
older diesel coaches, use an
Intellitec Bi-Directional Isolator
Relay Delay (BIRD) with a
separate solenoid. The BIRD
monitors both the chassis and
house battery and is the only
place in the coach where they
both merge. The BIRD only
functions when the engine or
generator is running or when the coach is connected to
shore power.

home page in Newgle.
Power Distribution
BATTERY DISCONNECT
Newmar uses an Intellitec
disconnect relay connected to the
battery bank to disconnect certain
loads when placing the coach in
storage. Keep in mind that not all
loads are disconnected. This is very
important to remember when a
coach is put into storage and is not
plugged into shore power. Before
placing the battery disconnect in the “off” position, make
sure the inverter (if equipped) is turned off.
When an older coach is stored while plugged into
shore power, do not use the battery disconnect. If the
battery disconnect is used, the chassis batteries will not
receive a charge from the converter or inverter/converter
combination. This is due to the coach battery wire being
disconnected, meaning the BIM or the BIRD will not
engage.
Some coach models have a manual rotary key switch
to disconnect power, which is located in the overhead
above the entry door. Most other coaches have a single
lighted switch located in the front overhead that turns off
the house voltage.
When the battery disconnect is ‘off’, meaning you
have disconnected components from the batteries,
there are still some loads on the batteries connected
to the hot side of the Battery Disconnect Relay. Some
of these loads may be Radio Memory, Entry Steps,
and LP Detector. These will draw from the batteries,
even when the disconnect is ‘off’. Pull the fuse for
each of the ‘HOT’ circuits to stop the batteries from
being drained.

BATTERY ISOLATION MANAGER (BIM)
All current Kountry Star, Super Star, Dutch Star, and
Ventana diesel coaches use a Precision Circuits all-in-
one Battery Isolation Manager (BIM). The BIM monitors
both the chassis and house battery and is the only place
in the coach where they both merge. The BIM only
functions when the engine or generator is running or
when the coach is connected to shore power.
To learn more, visit the Battery Isolation Manager home
page in Newgle.
When a 12 Volt wire is ran, most of the circuits are
protected with fuses or mini-breakers. These can be
located at various areas in the coach but are typically
located near the main breaker panel. The following
photos are examples only. However, they may also be
found in areas such as:
