TIFFIN MOTORHOMES –ALLEGRO BUS® Chapter 7 ELECTRICAL FEATURES
Circuit-Breaker Boxes
For the Allegro Bus, the 120 VAC breaker box and a separate 12 VDC breaker box
(Figure 7-1) are typically located beneath the refrigerator or in the bedroom [if inside the
vehicle]. The circuit breakers and associated fuses are installed to protect the electrical
system of the Allegro Bus from any overloads. Do not attempt to change the electrical
circuitry or to add appliances yourself.
Please consult an authorized Tiffin Motorhomes Dealership or Tiffin Motorhomes,
Incorporated in Red Bay, AL to determine whether any changes you desire are
appropriate and acceptable. Tiffin Motorhomes’ qualified staff of electricians can readily
determine whether any changes sought (e.g., CB radio, amateur radio, personal computer
system, and the like) are possible or not and can advise you on how best to realize these
enhancements. Please note that the 12VDC fuses are located in the same compartment in the
same distribution bay as the 120 VAC breakers. Fusing is provided for the following 12 VDC
circuits: All interior decorative and overhead lighting, water heater, TV switching box, slide
out lights, power roof vents, monitor panel, and the passenger-side console switch panel.
Additional 12 VDC fuse panels (Figure 7-2) are located in the front storage compartment on
the driver’s side; these fuse panels provide protection for the following circuits: Mirrors, fog
lights, hydraulic jacks, camera, wipers, docking lights, dashboard panels, spot light, power
seats, radio, step cover, satellite receiver, 30-ampere ignition breaker, 50-ampere ignition breaker, and dashboard air
circuit breaker. These fuse panels are protected by a plexiglass shield to prevent accidental short-circuiting of the 12
VDC power system. To protect this 12 VDC system further, DO NOT STORE anything in this compartment (e.g.,
toolbox) which may jostle around, break through the shield, and short out the 12 VDC system—if this system were
short-circuited, extensive damage and/or fire could result. Located on the passenger-side rear compartment is
another circuit panel, which contains the following circuit breakers: Slide-outs, 12 VDC disconnect, storage box lights,
and solenoids.

Warning
When any fuse is to be replaced, never replace a blown fuse with another fuse with
a larger current rating (e.g., amperes) than the original rating of the fuse being
replaced—to do so would probably damage circuits and/or equipment and cause
harm, injury, or death to nearby persons.
