AUXILIARY START SWITCH
Th e auxiliary start switch (Figure 9-2) is located on the switch
panel to the le ft of the steering wheel in front of the driv-
er’s-side console box (Figure 9-3).
Th is switch connects the Allegro Breeze coach batteries to the
chassis batteries—this allows the chassis batteries to “borrow”
power from the coach batteries to assist in starting the engine.
If the chassis bat-
teries cannot start
the engine by turn-
ing the ignition key,
hold down the bat-
tery-boost switch
for at least 60 seconds and retry starting the engine.
When attempting to use the auxiliary start switch function,
it is recommended that the owner press and hold the switch
for about 60 seconds before trying to start the engine. Th is
gives the two sets of batteries (house and chassis), a chance to
equalize prior to engaging the starter. Th e multiplex system
that controls most chassis functions will need to reach optimal voltage range to insure proper operation
as well.

BATTERY INSPECTION AND CARE
Th e 12-VDC electrical-power system consists of
two 6-VDC batteries wired in a series to provide
a fi nal 12 VDC system (Figure 9-4) providing up
to 200 Ampere-hours (A-hr) of service.
It is necessary to recharge the batteries occasion-
ally to increase the operational lives of the bat-
teries. It is also necessary to check the external
condition of the batteries on a regular basis.
Look for cracks in the battery case and cover.
Check the vent plugs and replace them if they are
cracked or broken. Keep the battery clean.
Since accumulations of dirt and acid residue
around the battery terminals may provide an
electrical path for discharging the battery, the area around the terminals should be cleaned periodically.
