REMOVAL
1. Ensure generator set is fully stopped, ENGINE CONTROL switch is OFF/RESET, Battery Disconnect Switch is
OFF, and DEAD CRANK SWITCH is OFF before proceeding.
2. Ensure there is no external cable connected to slave receptacle.
3. Open right and left side battery access doors.
4. Tag and disconnect battery cables 1C40 (Figure 1, Item 1) and 1A40 (Figure 1, Item 2) from left battery BT2
negative terminal (Figure 1, Item 3).
5. Tag and disconnect battery cable 12A40 (Figure 1, Item 4) from right battery BT1 negative terminal (Figure 1,
Item 5) and from left battery BT2 positive terminal (Figure 1, Item 6).
6. Tag and disconnect battery cables 24D40 (Figure 1, Item 7) and 24A40 (Figure 1, Item 8) from right battery
BT1 positive terminal (Figure 1, Item 9).
7. Remove three nuts (Figure 1, Item 10), lockwashers (Figure 1, Item 11), washers (Figure 1, Item 12), and pull
battery hold down angle (Figure 1, Item 13) off three threaded rods (Figure 1, Item 14).
8. Remove right battery BT1 (Figure 1, Item 15) and left battery BT2 (Figure 1, Item 16).
END OF TASK
TESTING AND CHARGING
NOTE
The testing and charging procedures apply only to the absorbed glass mat (AGM) type batteries
supplied with the TQG.
Do not mix AGM batteries with conventional flooded lead acid batteries, or reduced capacity,
shorter battery life, and possible undercharge problems may occur.
1. Allow battery to sit for at least 3 hours, preferably 8 hours. The battery must be disconnected from any load or
any other battery, and the ambient temperature should be approximately 70 degrees F (21 degrees C). Use
the battery load tester (4C-4911) to measure the open circuit voltage across the terminals for 12.8 to 13 Vdc,
indicating a fully charged battery.
2. If battery is not fully charged, charge the battery, using the SEALED or GEL setting on the battery charger,
before proceeding.
3. If battery is fully charged, apply a load of 550 amps for 15 seconds, using battery load tester (4C-4911). Check
the open circuit voltage again for a minimum or 9.6 Vdc.
4. If open circuit voltage is 9.6 Vdc or above, recharge the battery using the SEALED or GEL setting on the
battery charger.
5. If the open circuit voltage is less than 9.6 Vdc, battery is defective and must be replaced.
