SECTION 3 - BASE COMPONENTS
Battery Charger Check/Change Charging
Algorithm
The charger comes pre-loaded with nine algorithms for
batteries as detailed in Table 3-3. If your specific battery
model is not listed, please contact JLG.
Each time AC power is applied with the battery pack NOT
CONNECTED, the charger enters an algorithm select/dis-
play mode for approximately 11 seconds.
During this time, the current Algorithm # is indicated on
the YELLOW 'CHARGING' LED. A single digit Algorithm #
is indicated by the number of blinks separated by a
pause. A two digit Algorithm # is indicated by the number
of blinks for the first digit followed by a short pause, then
the number of blinks for the second digit followed by a
longer pause.
To Check/Change The Charging Algorithm:
1. Disconnect the charger positive connector from bat-
tery pack. Apply AC power and after the LED test,
the Algorithm # will display for 11 seconds.
2. To change algorithm, touch connector during the 11
second display period to the battery pack's positive
terminal for 3 seconds and then remove – the Algo-
rithm # will advance after 3 seconds. Repeat until
desired Algorithm # is displayed. A 30 second time-
out is extended for every increment. Incrementing
beyond last Algorithm moves back to first Algorithm.
After desired Algorithm # is displayed, touch the
charger connector to the battery positive until the
output relay is heard to click (~10 seconds) – algo-
rithm is now in permanent memory.
3. Remove AC power from the charger and reconnect
the charger positive connector to the battery pack. It
is highly recommended to check a newly changed
algorithm by repeating the above steps 1) and 3).

Battery Charger Removal/Installation

1. Remove the charger cover from the machine located
under the platform, see Section 3.2 on page 3-2.
2. Disconnect the positive (+) battery cable at the left
side battery under the left rear upper cover.
3. Disconnect the AC input, LED Status Indicator, Drive
Cut-Out Interlock, and DC Voltage Output to battery
wiring connectors from the top and bottom of the
charger assembly.
4. Remove the two (2) screws and washers from the
top bracket securing the charger to the frame
mount. Only loosen the two (2) screws on the bot-
tom of the bracket of the charger enough to slide the
charger out. Move the charger to a suitable work
surface.
