Action
Measure the voltage between the terminals of each new battery pack.
Note: Any battery pack set that does not meet these requirements must be
replaced (see CAUTION 3 on page 12-7).
Then the voltage reading must be
≥11.5 V dc on each 12 V battery pack
≥11.5 V dc on each 12 V battery pack
≥ 5.75 V dc on each 6 V battery pack
Remove the battery straps from the battery shelf if the battery to be replaced
is located in the swing frame.
Disconnect the battery harness from the battery string to be replaced.
Remove the complete battery string to be replaced (see CAUTION 3 on page
12-7).
Note: Each string consists of four,12 V dc or eight, 6 V dc battery packs.
Install the new battery string into the space vacated by the old batteries.
Note: Ensure that the batteries are arranged properly.
Dress the battery harness neatly into the battery compartment between the
batteries in such a manner that the cables are secure, free of kinks and twists
and formed so that they do not catch or snag on the equipment swing frame
as it is rotated to the closed position.
Connect the batteries installed in step 7 to the connectorized battery cable
harness at the battery end.
Note: Each battery harness is labeled to correspond to the correct battery
string.
Verify the integrity of the battery harness by checking for the proper battery
voltage on each connector at the battery interface connector field end of the
cable assembly.
Note: If a connector or battery cable assembly proves faulty (no voltage at the
BBP end), replace the cable assembly and re-check for cable integrity.
