TEST AND INSPECTION
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 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. 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.
END OF TASK
INSTALLATION
NOTE
Make sure batteries are oriented so that BT4 and BT2 have positive terminals toward battery
access doors, and BT1 and BT3 have negative terminals toward battery access doors.
1. Install battery BT3 (Figure 1, Item 26), BT1 (Figure 1, Item 25), BT2 (Figure 1, Item 24), and BT4 (Figure 1,
Item 23).
2. Position battery hold down angle (Figure 1, Item 21) on five threaded rods (Figure 1, Item 22) and install five
washers (Figure 1, Item 20), lockwashers (Figure 1, Item 19), and nuts (Figure 1, Item 18).
3. Remove tags and connect battery cables 24H40 (Figure 1, Item 16) and 24B40 (Figure 1, Item 14) to battery
BT3 positive terminal (Figure 1, Item 17).
4. Remove tags and connect battery cables 24B40 (Figure 1, Item 14) and 24A40 (Figure 1, Item 13) to battery
BT1 positive terminal (Figure 1, Item 15).
