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.

Batteries

Please refer to the Battery Basics article for more information.

Charge Bridge Solenoid

All current model 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.

Battery Isolation Manager (BIM)

All current Dutch Star, Ventana, and Ventana LE diesel coaches, as well as

gas coaches with 50 Amp electrical service, 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.
