ELECTRICAL FEATURES
GENERAL INFORMATION
There are two electrical systems used in your Tiffin Wayfarer Motorhome. These are the 12V
DC (VDC) system and the 120V AC (VAC) system. Most standard appliances require the 120V
VAC system, while the majority of the lighting systems used in your Wayfarer use the 12V VDC
system.
The electrical power for the 12V VDC system is supplied by the house batteries of the Wayfarer.
Those batteries are charged by a power converter. The engine also charges the house batteries
when the engine is running.
(NOTE: The house batteries switch does not have to be on while
the engine is running to receive a charge from the alternator).
The electrical power for the 120V VAC is
supplied by the 30AMP shore power cord (Figure
72 . 2 ) when the Wayfarer is connected to an
external power source or when the on-board
electrical generator is in operation.
The inverter can also supply 120V VAC electrical
power (to limited outlets and limited appliances).
The items on board the Wayfarer that are powered
by the inverter are limited to Televisions and the
Refrigerator.
The inverter transforms the 12V VDC electrical
power from the house batteries into120V VAC
electrical power needed for the basic appliances.
CAUTION: Failure to turn off all of the 120V VAC appliances when starting the or
stopping the on board electrical generator may damage the transfer switch and/or
electrical appliances.
To connect the Wayfarer to an external source of
120V VAC electrical power, it is first
recommended that the main 30AMP circuit breaker
be placed in the "OFF" position (Figure 73.2).
This is done to prevent any power surge upon
connecting the motorhome to the external power
source.
Unwind the power cord from the electrical
compartment located in the in an external
compartment (Figure 72.2).
