The automatic transfer switch has a delay of

located on the drivers side rear most storage
compartment.

Automatic Transfer Switch
If the unit is plugged into shore power but there is no power to the motorhome, then make sure
the shore power outlet has power. If power is present, this may indicate that the automatic
transfer switch is sensing an open neutral condition. Start the generator, if the motorhome
power is restored then either the shore plug or the outlet may be defective (the neutral line may
be broken).
If there is no power to the motorhome from either shore power or the motorhome generator,
then check the generator circuit breaker. If the circuit breakers are not tripped in the generator
or the coach, the transfer automatic transfer switch may need to be replaced.
For more detailed information, on the automatic transfer switch, please refer to the specific
manufacturers owners instructions found in the owners information package.
CAUTION: Service to the automatic transfer switch is to be done by a qualified
service technician. DO NOT attempt to remove the automatic transfer switch cover
box unless the shore power cord is unplugged and the generator is off.
NOTE: Be sure air conditioning units are "OFF" before connecting or
disconnecting to or from 30AMP shore power.
