ECHARGE SYSTEM VOLTAGE CHECK
ECHARGE SYSTEM VOLTAGE CHECK
The battery recharge system consists of a threephase gene-
rator and a permanent-magnet flywheel.
The generator is directly connected to the voltage regulator.
The latter is in turn directly connected to earth and to the
battery positive terminal via the 15A protection fuse (no. 7).
The system is therefore not connected to the ignition key-
switch.
The three-phase generator allows for considerable rechar-
ging power and, at low rpm, offers a good compromise bet-
ween supplied power and idle speed stability. For this rea-
son, it is essential that the slow running speed is adjusted as
specified.
Connect an ammeter's induction clamp to the positive ter-
minal of the voltage regulator, measure the battery voltage
and, by switching the headlight on, wait until the voltage
settles at approx. 12 Volts. Start the engine and measure the
current supplied by the circuit with headlight on and engine
at high rpm.
If the current is below 10A, repeat the test using, alternately,
a new regulator and/or stator.

NSPECTION
For information on how to carry out the functional and re-
sistive check of the component, refer the engine section of
this manual. Regarding the automatic choke device power
supply, keep the system connector attached and check that
battery voltage is present between the two terminals, with
engine running (see figure).
If there is no voltage, connect the multimeters negative termi-
nal ti earth and the positive terminal to the with the ignition
switch turned onto the ON position, check for the presence
of battery voltage. If no voltage is detected, check the wiring
connected with the ignition switch and the two fuse 15A.
If voltage is present, repeat the check from the ignition con-
trol unit connector.
