a. Monitor the charger output voltages at A8TP2 (positive sup-
ply) and A8TP3 (negative supply) while allowing the chargers
to recharge the battery tray(s) until each test point rises to
|205| ±1.0 VDC. Note: Charging to these levels may take up
to 2 hours. If these levels cannot be achieved, check the
integrity of the batteries in the affected side of each tray.
b. Once this level has been achieved at A8TP2, adjust A8R70 to
produce Output Limiting, which is indicated when yellow LED
A8D7 begins to blink.
11. Similarly, once this level has been achieved at A8TP3, adjust
A8R66 to produce Output Limiting, which is indicated when yel-
low LED A8D25 begins to blink.
