Park the truck on level ground and block the
wheels with wooden wedges;
Fully lower the fork and press the emergency
stop switch.
Turn off the key switch;
Open the cover and check the controller.
-
-
Even if key switch is turned off, the controllers
are still energized.
Before checking or repairing the controllers,
m a k e s u r e t h e b a t t e r y p l u g h a s b e e n
unplugged and the electrical circuit is
disconnected.
9.1.1 Check the Voltage of Battery
-
-
Unplug the battery plug;
Measure the battery voltage with a multim-
eter: black probe (-) connected to (-) terminal
of battery plug; red probe (+) connected to
the (+) terminal of battery plug. Read the
voltage reading on the meter.
Battery
Voltage Judgment
24V
Greater than 24V Normal
Less than 24V
Needs to be
charged
Enter Monitor Menu to check the battery
voltage.(see Section 8.9)
If the battery voltage is still abnormal after being
charged: open the battery compartment, check
the voltage of each battery and its connection
circuit respectively:

NOTE
-
Identify if the battery voltage is normal
according to the measured voltage.
As shown in the following table:
1)
2)
Check if the voltage of single battery is
normal;
(See Service Manual : Maintenance-free
Battery)
Check if the cables for connections between
each battery are normal, check for open circ-
uit and if the connection between connectors
is secure.
-
Battery leakage check: disconnect the battery
connection, black probe (-) connected to
(-) terminal of battery plug; red probe (+)
connected to the chassis. Read the voltage
reading on the meter.
No voltage (0V): normal;
With voltage: battery leakage (remove battery
compartment, check each battery and cables)
