13.Charging abnormal(battery over charging or over discharging)
Check and adjust Trouble condition The reason
Measure battery’s
Voltage then start
engine
Check voltage rectifier
Plug is loose or not
Check the voltage
Between chassisΘand
The red cable♁of
Voltage rectifier
Check the resistivity
Of A.C. generator coil
Start engine, connect
green cable to
Chassis, then measure
the voltage between
chassisΘand red cable♁
of voltage of
rectifier
Check the connection
Of the cable of
Voltage rectifier
Check the resistivity
Of the body of
Voltage rectifier
Voltage remain
The same
good loosen
Voltage goes up
To normal value,
But after engine
Stop, the voltage
Goes down again
good No voltage
battery is dead
battery malfunction
poor connection
red cable disconnected
voltage rectifier
malfunction
white cable disconnect
defective coil
normal abnormal
poor connection
A.C. generator’s
charging abnormal (over charging) white cable
disconnected
Voltage higher
Than specification
Voltage normal
good Poor connection
Out of spec
cable poor connection
poor connection of
green cable
