• Next, hold the switch down for one minute and turn the key on.
The battery voltage gauge on the dash should indicate at least 12
Volts. If voltage is sufficient with the Auxiliary Start switch held
down, start the engine.
• If the engine fails to crank, or fails to crank quickly, the chassis
battery may be depleted and the motorhome will require jump-
startings or an external charger hooked to the chassis battery. When
using jumper cables to start the engine, the cables must connect in
a parallel configuration. That is positive (+) to positive (+) and
negative battery (-) to negative chassis (-). Always connect the pos-
itive (+) before connecting the negative (-). To prevent arcing
when disconnecting the cables, disconnect the negative (-) before
disconnecting the positive (+).
WARNING: Batteries can emit explosive gases. Always ven-
tilate the battery compartment prior to performing work or
service on the batteries. Extinguish all smoking material and
keep all open flame and spark producing devices away from
battery area.
CAUTION: A large amount of electrical current is required
to jump-start an engine. The sizes of the battery, alternator
and jumper cables supplying the "jump" are current limit-
ing factors. Voltage fluctuations that occur during a jump-
start procedure can damage sensitive electronic equipment
and charging systems. Wait a sufficient amount of time for a
surface charge to build before attempting to crank an engine
when using a jump-start procedure. If uncertain about per-
forming a jump-start procedure, contact a service techni-
cian. Damage and personal injury can occur if this not pro-
cedure is not performed correctly.
