NOTE: The microwave and air conditioner (and optional DSS) will only operate o n
IIOV,
while the refrigerator will operate on
I I O V , 12V
or LPG.
12V SYSTEM (COACH)
Most of the appliances in the Chinook motorhome run off of 12V power. As noted in the
previous section, the two exceptions are the microwave and air conditioner, which will only run off
of I 10V power. 12V power is supplied through the 100 amp power converter (running off of 110V
shore power or the generator) or through two coach batteries. Some auxiliary 12V power is also
supplied from the roof mounted solar panel.
2000 Watt Prosine I nverter1Converter
The inverter allows you to run some 110v AC appliances without being connected to shore power.
Inverters work by producing a 60 hertz sine wave able to safely power any 110V appliance.
Prosine inverters come with a monitor which will shut down the inverter when battery voltage
reaches 12V DC, or when it detects shore power. Using the inverter can be a very power intensive
process and should be used with discretion. The built-in power converter is required to convert
110V power to 12V power. When shore power is available or the generator is turned on, 12V
power is supplied through the power converter to all appliances including power to charge the
coach batteries. As noted earlier, the power converter is located in the bottom of the wardrobe.
The converter supplies 100 amps to the 12V system. It has 4 stages, and automatically switches
between bulk, absorption, float, and quick charging stages, as needed
Fuse Panel
Ail 12V circuits are protected with properly rated fuses or automatic reset circuit breakers.
There are three exterior circuit breakers. One breaker is a 200 amp panel for the slide pump, one
100 amp panel for the generator, and one 100 amp panel for the main power network. If the
breaker continues to trip, however, the system should be checked by a service technician to
determine the cause.
The main 12V converter circuits are protected by fuses located inside the converter.
