CHECKING THE CHARGING SYSTEM
– Start the engine.
– Using the voltmeter function of the multimeter, connect
the positive lead to the positive terminal of the battery,
and the negative lead to the negative terminal of the
battery.
– At 6000 rpm voltage must be included between 13.5
and 15 V.
TROUBLESHOOTING
A.INSUFFICIENT RECHARGE VOLTAGE
– Check the fuse and, if necessary, replace it.
– Check the cable connections on regulator, flywheel,
battery and fuse.
– Check the battery (see below).
– Check the generator (see below).

B.EXCESSIVE RECHARGE VOLTAGE
– Check the voltage regulator.
– Check the cable connections.
C.IF NO VOLTAGE REACHES THE LOADS UNDER
DIRECT CURRENT (green/red cables)
– Check the fuse and if necessary replace it.
– Check the ground connections on regulator, flywheel,

– Check the battery (see below).
– Check the generator (see below).
– Check the ignition switch (see p. 96) and its connections.
D.IF THE SYSTEM FUNCTIONS IRREGULARLY
– Check the earth connections.
TEST DATA
GENERATOR
– Disconnect the two-way connector from the generator.
– Start the engine and bring it to 6000 rpm.
– Using the alternating current function of the multimeter,
measure the voltage between:
• orange cable and generator earth = value over 41.2
V.
• yellow cable and generator earth = value over 35V.
– Using the alternating current ammeter function of the
multimeter, measure the current between:
• orange cable and generator earth = value 8 - 10 A.
• yellow cable and generator earth = value 8 -10 A.
BATTERY
– No-load voltage 12.5 ± 1V.
– Make sure that there are no signs of sulphation.
Replace if necessary.
