• Next, start the generator. This may require using the Battery Boost switch for the generator
to start from the engine battery. Once the generator is operating, the electrical combination
of the generator, inverter and/or converter will charge the batteries.
• Allow the generator to run approximately ½ hour before attempting to start the engine.
• After ½ hour of generator operation, leave the generator on and hold down the Battery Boost
switch for one minute. Release the switch for one minute, then press the switch again for one
minute. Alternate this cycle three to five times to avoid overheating the Boost solenoid.
• Next, hold the switch down and turn the ignition on. The battery voltage gauge on the
dash should indicate at least 12 Volts. If voltage is sufficient with the Boost switch held
down, try to 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-starting 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 positive (+) before connecting the negative (-).
To prevent arcing when disconnecting the cables, disconnect the negative (-) before discon-
necting the positive (+).
WARNING:
Batteries can emit explosive gas. Always ventilate the battery compartment prior to
any work or service to the batteries. Extinguish all smoking material and keep all
open flame and spark producing devices away from battery area.
Jump Starting using an external source:
1. When using an external electrical source to connect to the chassis battery, turn the main
battery disconnect switches
OFF
prior to hooking up the jumper cables.
2. Hook up the cables then wait several minutes to allow a surface charge to build in the chas-
sis battery before attempting to start the engine.
3. Turn
ON
the battery disconnect switches and attempt to start the engine.
DO NOT crank
the engine more than a few seconds
