Battery recharge system

The battery recharge system includes a three-phase
generator with 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 30A fuse.
Therefore, the system is not connected to the ignition
switch.
The three-phase generator allows considerable re-
charging power and a fair compromise between sup-
plied power and slow running stability at low rpm.

Recharging system

Searching for leaks

1) Before measuring the output voltage, ensure that no
electrolyte is leaking from the battery.
2) Turn the ignition key to the OFF position and connect
the tester terminals between the battery negative
pole (-) and the black cable.
3) Detach the black cable from the battery negative
pole (-) while keeping the tester terminals connected.
4) With the ignition key still in the OFF position, the
ammeter should read ≤ 0,5 mA.

Checking the charging voltage

Warning
- Before performing the check, ensure
that the battery is in good condition.
1) Put the vehicle on the central stand.
2) With the battery properly connected to the circuit,
position the multimeter prods between the battery
terminals.
3) Start the engine with all lights out and rev up while
measuring the voltage.
VOLTAGE: 14.0-15.0V at 5,000 rpm.
