A.
Battery Reinstallation
CAUTION: THE BATTERY PACK CONTAINS ELECTROSTATIC DISCHARGE SENSITIVE (ESD)
COMPONENTS AND IT MUST BE HANDLED WITH CARE. IF POSSIBLE, WEAR A GROUNDED
WRIST STRAP WHEN HANDLING THE BATTERY PACK DURING INSTALLATION
ACTIVITIES. TAKE PARTICULAR CARE TO AVOID TOUCHING THE EXPOSED CIRCUIT
BOARD AND CONNECTOR PINS ON THE BOARD.
1)
This subtask applies to reinstallation of an existing battery that was removed for inspection and testing.
2)
See Figure 23 Battery Pack Installation.
Figure 23 Battery Pack Installation
3)
Apply a thin coating of non-petroleum based silicone grease, such as GE G-635, to the rubber seal to
facilitate installation and allow the ELT and battery pack to slide together without binding on the rubber
seal.
4)
Lay the battery pack and ELT on their sides, such that the two components are aligned, but separated
enough to allow the electrical connections to be made.
5)
Connect the ELT lead 8-pin connector to the header on the battery pack circuit board.
6)
Connect the power harness 2-pin connector to the recessed connector inside the ELT body.
7)
Reset the ELT
by toggling the ELT local control switch to “ON” and back to “OFF” after 1
-2 seconds.
NOTE:
This step is necessary because the ELT will occasionally activate when power is connected
to it in Step 6.
