TIFFIN MOTORHOMES –PHAETON® Chapter 7 ELECTRICAL FEATURES

Caution
Never replace a fuse with a fuse rated larger than that which originally came from
the factory. To do otherwise will cause serious damage, overheating of the wiring,
and possible ignition of nearby materials resulting in a fire.
Automatic Transfer Switch
The resettable circuit breakers (Figure 7-14) are located within 18 inches of the
source of power; that is, the converter and the battery. When the circuit breakers are
shut down or electrically tripped, they must be manually reset. To find the circuit
breakers, follow the line from the battery or converter approximately 18 inches—this
may lead to a junction box or to a cabinet inside the Phaeton or to a similar location.
As needed, manually reset the circuit breaker or breakers as shown in the
accompanying figure. Be careful when working around these connections as an
accidental, electrical short to ground (i.e., momentarily connecting the “positive” or
“hot” terminal to any part of the chassis) can be hazardous and harmful.
Fuse Blocks
Some of the electrical circuitry within the motor home is protected by various fusing systems. Some of these fuse blocks
are immediately accessible on the driver’s side exterior compartment. These fuse blocks (Figure 7-15) protect some of
the major electrical systems of immediate concern to the driver.
Should there be any electrical failure of these components or systems, the first
diagnostic or troubleshooting procedure should be to check the fuses and have
available replacements to replace any blown fuses, as may be warranted.
Also the Phaeton contains a computerized diagnostic center usually attached to the
steering column under the dash. This center permits a computer to be connected to
the on-board 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.
Whenever a fuse has been “blown” and is to be extracted and replaced, it is good practice to examine the wiring going
to that particular fuse to see if there is any noticeable degradation (e.g., wiring insulation nicked, missing, or melted)
which may indicate damage beyond the fusing proper.
