Yes No
Failure diagnosis procedure when the storage battery can not be charged
The storage battery can not be charged
The resistance value is smaller than
standard value
Short circuit of
charge coil
The resistance value is infinite
The resistance value is equal to
standard value
Short circuit of charge
coil or its output wire
Place the multimeter in the 0V~20V DC
voltage, measure the voltage of the insert
connector to the conductor terminal of storage
battery (generally red wire or red/white wire)
and negative pole
The circuit from the magnetor to
commutator
or commutation
regulator is in poor contact or
broken
No voltage indicates Voltage indicates
Circuit from the
insert
connector
to storage battery
is broken
Use the ohmmeter to test the
commutator or test if the
commutation regulator fails
Disconnect the insert connector of magnetor wire
bundle and the complete vehicle cable, use the
ohmmeter to measure the resistance between the
output wire ends of charge oil, and check if it
meets the standard value
Connect the insert connector between the magnetor
wire bundle and the complete vehicle cable, disconnect
the insert connector between the commutator or
commutation regulator and the complete vehicle cable
Use the ohmmeter to measure that if the resistance
between the output wire ends of charge oil in the insert
connector is equal to the resistance of the charge coil
itself
