BATTERY
This unit is of negative ground. DO NOT connect in reverse.
Always maintain battery fluid level between the specified
marks. Battery life will be shortened if the fluid levels are
not properly maintained. Add only distilled water when
replenishment is necessary.
DO NOT overfill. Check to see whether the battery cables
are loose. Poor contact may result in poor starting or
malfunctions. ALWAYS keep the terminals firmly tightened.
Coat the terminals with an approved battery terminal
treatment compound. Replace the battery with only the
recommended type battery. The battery type used in this
generator is BCI Group 27.
The battery is sufficiently charged if the specific gravity
of the battery fluid is 1.28 (at 68°F). If the specific gravity
should fall to 1.245 or lower, it indicates that the battery is
dead and needs to be recharged or replaced.
Before charging the battery with an external electric source,
be sure to disconnect the battery cables.
Battery Cable Installation
ALWAYS be sure the battery cables (Figure 38) are
properly connected to the battery terminals as shown below.
The red cable is connected to the positive terminal of the
battery, and the black cable is connected to the negative
terminal of the battery.
CAUTION
ALWAYS disconnect the negative terminal FIRST and
reconnect the negative terminal LAST.

INSPECTION/SETUP
When connecting the battery:
1. NEVER connect the battery cables to the battery
terminals when the Auto Start/Stop Switch is in either
the AUTO or MANUAL position. ALWAYS make sure
that this switch is in the OFF/RESET position when
connecting the battery.
2. Place a small amount of battery terminal treatment
compound around both battery terminals. This will
ensure a good connection and will help prevent
corrosion around the battery terminals.
NOTICE
If the battery cable is connected incorrectly, electrical
damage to the generator will occur. Pay close attention
to the polarity of the battery when connecting the battery.
CAUTION
Inadequate battery connections may cause poor
starting of the generator, and create other malfunctions.
ALTERNATOR
The polarity of the alternator is negative grounding type.
When an inverted circuit connection takes place, the circuit
will be in short circuit instantaneously resulting in alternator
failure.
DO NOT put water directly on the alternator. Entry of water
into the alternator can cause corrosion and damage the
alternator.
WIRING
Inspect the entire generator for bad or worn electrical wiring
or connections. If any wiring or connections are exposed
(insulation missing) replace wiring immediately.
PIPING AND HOSE CONNECTIONS
Inspect all piping, oil hose, and fuel hose connections for
wear and tightness. Tighten all hose clamps and check
hoses for leaks.
If any hose (fuel or oil) lines are defective replace them
immediately.
