3-4 Troubleshooting
3-4-1 Drive motor
The problem Probable cause
The drive motor is not working Switch not off (battery connector, key switch,
handle access switch, accelerator) :
Turn off switch. If it still does not work, use a
voltmeter to test the power supply on the control
panel and the current on each switch.
Bad signal. Fuse blown:
Check the battery connection. Check the
connection of the battery connector. Check fuses,
drives and logic. Replace the retaining wire if it
fuses.
Check the drive motor and control panel for
possible fuses.
Some of the reasons are:
Operating under excessive load, the current limit
is too high
Low battery voltage:
Check the battery terminal voltage. If it's too low,
charge the battery.
The drive motor is not working Excessive wear on carbon brushes(Spring press to
the lowest level of carbon brush)。
Traction does not operate during normal
operation, but hydraulic operation is normal
A defective brake caused excessive resistance.
The increased heat causes the motor to stop
running. Check brake adjustment。
Heavy traction load: Reduces duty cycle load.
