Operation
If the needle is in the lower red sector around 12.5 V, the charging system
does not work correctly and the battery is not fully charged.
If the needle is in the upper red area above 15 V, there is also a problem; the
charging system overloads the battery. Have the vehicle checked by a profes-
sional.
d) Now, turn on full beam headlights and windscreen heater and set fan to the
highest level. The value should not change for more than 0.1 to 0.3 V.
If the value increases or decreases for more than 0.3 V, have your charging
electrical equipment such as headlights, regulators, brushes, drive-belts,
cables, mass points or cable plug connectors examined by a mechanic.
