TIFFIN MOTORHOMES –ALLEGRO BUS® Chapter 7 ELECTRICAL FEATURES
If the unit is plugged into shore but no power to coach then make sure the shore outlet has power. If power is present
this may indicate the unit is sensing an open neutral condition. Start the generator. If power is restored to the coach
then neither the shore plug or outlet may be defective (the neutral line may be broken).
If there is no power to coach from shore or generator then check the generator circuit breaker. If the circuit breakers
are not tripped in generator or coach, replace transfer box.
For more detailed information on the automatic transfer switch, please refer to the specific owner’s instructions found
in the owner’s information package.
Electric Power Cord Reel
The electric power cord reel (Figure 7-19), allows you to manually extract the power
cord reel as needed. To retract the power cord, hold the button in on the handle until
the power cord is fully retracted.
Fuse Blocks
Some of the electrical circuitry within the motor home is protected by various fusing
systems. Some of these fuse blocks are accessible in the front outside compartment.
Underneath the dashboard is an enclosure which contains fuse blocks. These fuse
blocks protect some of the major electrical systems of immediate concern to the driver
such as the power seats (driver’s and passenger’s), spot light, mirrors, camera, radio, and
various extra fused positions.
Should there be any electrical failure of these components or systems, the first
troubleshooting procedure should be to check the fuses and have available replacements
to replace any blown fuses, as may be warranted.
Also the Allegro Bus contains a computerized diagnostic center, located beneath the access panel which is
under the dash attached to the steering column, for the engine of the motor home. This center permits a
computer to be connected to the onboard diagnostic center monitoring many of the operating functions and
parameters of the engine so that the current operating status of the engine can be determined and any
anomalies or problems may be noted.
This diagnostic tool enables the motor home owner to maintain an updated status of the engine so that the
overall reliability of the motor home can be maintained.
As an aid to extracting and/or installing fuses in the fuse blocks, one may wish to buy an inexpensive fuse
puller at any electronics or hardware store. This tool makes the installation or removal of fuses much easier and
prevents inadvertent damage to nearby fuses or the fuse block itself.
