CHECKING OF THE ALTERNATOR MOUNTED ON THE VEHICLE.
The operation of the alternator can be checked on the vehicle, by connecting a voltmeter
to the battery plugs.
At rpm of 2000 rot/min without consumers, the voltage read on the instrument must be
about 14,6 +/ - 0,1 V .
At same rpm ( 2000 rot/min ) with consumers ( headlights, air conditioner,windscreen
wipers ) the voltage read on the instrument must be between 13,5 and 14,5 V. If the measured
values are not correct, perform the checking of the alternator on bench.

Checking is performed by means of a voltmeter connected according to the above
diagram,where you can identify:
B = battery , V = voltmeter, A = alternator , R = voltage regulator , Key = ignition
contact, Tb = instrument board.
For a voltage of 12,8 V read on instrument,
the needle of the voltmeter on the instrument
board must be placed in the left side of the
central area.
For a voltage of 13,5 V read on instrument,
the needle of the voltmeter on the instrument
board must be placed in the middle of the
central area ( white area ).
