11.2 Checking the system
1) make sure that the connections between the regulator and
alternator are correct and in good conditions
2) detach the wire from the remote control switch from the
terminal and fit on a d.c. amperometer ( ,fig. 44)
3) coconnect a d.c. voltmeter to the battery terminals ( , fig.
44)
4) make a few no-load starts or introduce a 80 80 80 80 80

load at the battery lugs to keep the battery voltage below

5) accelerate the engine to a 3000 rpm 3000 rpm
3000 rpm 3000 rpm
3000 rpm rate. The current
indicated on the amperometer must correspond to the
values in fig. 45.
6) disconnect the load (if any) and keep the engine at the
above mentioned rate for a few minutes. The battery
voltage must progressively increase until reaching about
14.2 V
14.2 V 14.2 V 14.2 V 14.2 V. Meanwhile, the charge voltage must drop to a
minimum value of about 2A
2A 2A 2A 2A, with a speed determined by
the battery charge condition.
7) if charge current is missing or is less than the given values,
check the alternator and replace the voltage regulator if
necessary.
11.3 Checking the alternator
With the engine at a standstill, disconnect the alternator wires
from the regulator and check:
1) using an ohmmeter, that the windings (fig. 46), null
resistance) and the insulation between wires and ground
(fig.47, infinite resistance) are unbroken. Replace the
stator if interruptions are discovered;
2) with a voltmeter, the voltage between the two yellow wires
(fig. 48). Accelerate the engine to 3000 rpm 3000 rpm 3000 rpm 3000 rpm 3000 rpm. The voltage
must be 33V 33V 33V 33V 33V.
If the values are more than 10V less than this, it means that
the rotor is demagnetized and that the alternator must be
replaced.
Warning: Warning:
Warning: Warning: Warning:
1) the alternator does not deliver current when the yellow
cables are isolated
2) the alternator burns out if the yellow wires are grounded
3) the regulator may be damaged if the ground connection or
electrical connections are made in a slapdash way.
4) the alternator and regulator will immediately burn out if the
battery connections are inverted.
11.4 Ring gear
Make sure that the teeth of the crown wheel are not worn or
damaged. Heat the starting ring gear to a temperature of 200-
250 °C before fitting it on to the flywheel .
