Diagnosis on battery charging failure
Battery charging
failure
Resistance value lower
than standard value.
Short circuit of
charging coil
Infinite resistance
value.
Resistance value in accordance
with standard value.
Open circuit of charging
coil or output conductor.
Set the multimeter to DC voltage 0V~20V;
measure the voltage between the conductor
terminal (connector to battery) (normally red
wire or red/white wire) and the negative pole. Bad connection or open circuit
between the electromagnetic motor
and the rectifier or inside the circuit of
rectifier regulator
No voltage Voltage
available
Open circuit between
the connector and the
battery. Check whether the rectifier or the
rectifier regulator is broken down
with an ohm meter.
Remove the connector between the conductor bundle
of electromagnetic motor and the cable assembly;
measure the resistance between the output conductor
terminals of charging coil and check whether it is in
accordance with the standard.
Connect power to the connector between the conductor
bundle of electromagnetic motor and the cable
assembly; cut off the connector between the rectifier or
rectifier regulator and the cable assembly.
Measure the resistance between the output conductor
terminals of charging coil of the connector and check
whether it is in accordance with the standard.
