2.6 Battery Charger
The generator set is equipped with a 6-amp
float/equalize battery charger to maintain the engine
starting battery. The charger’s power cord must be
connected to a 120 VAC power source. Figure 2-5
illustrates the battery charger.
The battery charger uses an AGS 10 inline fuse. The
fuse is located in the battery lead. See Figure 2-5.
2.6.1 Battery Charger Operation
Figure 2-6 illustrates the three-stage charging method.
Red and green LEDs indicate charger operation. The
chart in Figure 2-7 describes the LED indicator
operation during each stage of the charging process.

Display Operating Condition
Red ON
Green OFF
When the red LED is on, it indicates the battery is discharged and the battery charger is recharging at the BULK rate
(stage 1). This charging rate is 6 amps. While the red LED is on, the voltage measured (with the battery charger on) will be
11.8--14 volts.
If the red LED stays on for more than 24 hours, refer to Section 4.5 in this manual.
Red ON
Green ON
When both the green and the red LEDs are on, the battery charger is charging at an ABSORPTION rate of between 1.5 and
5 amps (stage 2). This mode of charging gradually tops off your battery, and reduces harmful sulfating. While both LEDs
are on, the voltage measured (with the battery charger on) should be approximately 14.0--14.5 VDC.
If both LEDs stay on longer than 24 hours, refer to Section 4.5 in this manual.
Red OFF
Green ON
When the green LED is on, the battery charger is charging at a FLOAT or MAINTENANCE rate of less than 1.5 amps
(stage 3). Your battery is now 90% charged and ready for use. This float charging current will gradually decrease to as low
as 0.1 amps as the battery reaches 100% charge. It will now be kept at full charge without overcharging.
If the green LED stays on when your battery is known to be low, refer to Section 4.5 in this manual.
