6.3.1 CHECKING THE RECHARGING VOLTAGE

N
Check the electrolyte level, see 2.3.1 (CHECKING THE
ELECTROLYTE LEVEL).
N
Check battery voltage, see 2.3.3 (RECHARGING THE
BATTERY).
N
Start the engine and let it run until it reaches 5000 rpm.
N
Set the light switch to "(" and dimmer switch to "7".
N
Using a pocket tester, measure the direct voltage be-
tween the positive (+) and negative (–) terminals.
If the tester indicates voltage values lower than 13V or
higher than 15V:
N
Check the loadless operation and the continuity of the
alternator, see 6.3.2 (CHECKING THE ALTERNATOR
LOADLESS OPERATION) and 6.3.3 (CHECKING THE
ALTERNATOR CONTINUITY). Also check the voltage
regulator, see 6.3.4 (CHECKING THE VOLTAGE
REGULATOR).
Second figure key
1) Voltage regulator
2) Battery
3) Ignition switch (2 – 1 – &)
4) 20A fuse
Standard charging voltage:
13 ÷ 15 V (c.c.) at 5000 rpm.
6.3.2 CHECKING THE ALTERNATOR LOADLESS
OPERATION
N
Remove the left cover, see 7.1.4 (REMOVING THE
RIGHT AND LEFT SIDES).
N
Disconnect the alternator cable connector (5).
N
Start the engine and let it run until it reaches 5000 rpm.
N
Using a pocket tester, measure the voltage (alternating
current a.c.) from the three internal male terminals [yel-
low cables (G)] in rotation.
If the value indicated by the tester is lower than 70 V,
the alternator is faulty.
Standard loadless voltage:
more than 70 V (a.c.) at 5000 rpm.
