detected.
Charging voltage too low:
Check whether the drive belt is slipping
or whether the cable connection between
the alternator and battery is normal or
not. If the drive belt and cable connection
are OK, follow the vehicle manufacturer's
recommendations to rule out alternator
failure.
Charging voltage too high:
The output voltage of the alternator is too
high. Please contact a specialist workshop
to check the charging system. The usual
voltage for vehicle regulators is 14.7
±0.5 V. A high charging voltage leads to
overcharging of the battery and shortens its
service life; it can also lead to malfunctions.
