CHECKING THE CHARGE VOLTAGE

"
After having completely charged the battery, see 2.5 (BATTERY).
"
Connect a multimeter between the positive (+) and negative (-) battery
terminals.
"
After starting the engine, disconnect the fuse and connect an ammeter to
the ends of the wires.
"
Using a revolution counter, accelerate and measure the charge voltage and
current.
13.0 ~ 15.0 V / 1.0 A below 5000 rpm.
If the measured value is incorrect, check the rectifier, see 5.3.3 (RECTIFIER).
5.3.3

RECTIFIER

"
Disconnect the four-way connector (1) (coloured green).
"
Set a multimeter to the x 1 M. range and measure the resistance of each
terminal from the rectifier side (inner male terminals).

This test method provides an approximate measure of resistance. Where
possible, fit a substitute rectifier known to be in good working order to
test the charge system.
If the reading found deviates from the specified value, change the rectifier.
