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 level is
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 malfunctions or poor
starting. ALWAYS keep the terminals firmly tightened. Coat
the terminals with an approved battery terminal treatment
compound. Replace the battery only with the recommended
type of battery.
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, the battery is dead and needs
to be recharged or replaced.
Be sure to disconnect the battery cables before charging
the battery with an external electrical source.
Battery Cable Installation
Connect the two 12-volt batteries in series (24-volt system)
as shown in Figure 47. Make sure the battery cables are
properly connected to the battery terminals. Connect the
red cable to the positive terminal of one battery, and
connect the black cable to the negative terminal of the
other battery.
CAUTION
ALWAYS disconnect the negative terminal first and
reconnect the negative terminal last.

Figure 47. Battery Connections
When connecting the battery:
1. NEVER connect the battery cables to the battery
terminals while 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 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.
NOTICE
Inadequate battery connections may cause poor
starting of the generator and create other malfunctions.
