Proceed by measuring the resistance between
contacts 3 (White) and 2 (Black) from the voltage
regulator (with the connector detached).
If the reading differs excessively from the figures
shown, replace the regulator as short-circuited.
b) Battery not recharging (regulator circuit inter-
rupted).
To check for the presence of faults on the recharg-
ing section of the voltage regulator, it is necessary
to initially operate on the battery, using two testers
(one for voltages and one for currents), as shown
in the second figure, and follow the operations giv-
en below:
Start the engine (connecting, temporarily, the red
wire to the positive terminal of the battery, so to
avoid damaging the instrument measuring the cur-
rent).
Check the voltage at idle is at least 13V (charged
battery) and the recharge current is 1.5 - 2A with
the lighting system and the choke device exclu-
ded, as described in the chapter "CHECKING THE
VOLTAGE REGULATOR".
As the engine speed increases, so do the recharge
current and voltage, and at speeds above 4,000
rpm, a recharging current of approx. 4.5A must be
observed; reactivating the lighting system and
choke device, and operating the stop light and
horn, current values of
≥
5A may be found, with
voltage readings of 14 - 14.5V (regulator threshold
voltage).
If the readings do not match the above figures,
replace the regulator; otherwise check wiring
and connections.
