FAULT 3: Blown main fuse
After checking that there are no short-circuits in the
system towards earthing with the engine off and
the regulator connector detached, replace the reg-
ulator because it is certainly inefficient, and re-
place the protection fuse.
Following the replacement, measure the current
and the recharging voltage on the battery end. The
values detected must be 1.5 ÷ 2 A and 13 V at 3000
rpm.
FAULT 4: Battery does not recharge
a) Make the scooter move and disconnect the bat-
tery positive lead. Place the tester to detect alter-
nating voltages between the connection of the
yellow cable (8) on the regulator and the black ca-
ble (6) to check that the voltage supplied by the
generator at 3000 r/1' is within 26 ÷ 30 V. In case
of irregularities, replace the stator; otherwise, pro-
ceed to point b).
b) Yellow cable (1) connected to the regulator. In-
sert an ammeter between the Red cable (2) of the
stator and the battery and check, with the tester,
that the current supplied at 3000 r/1' and with the
battery between 12 and 13 V is about 1.5 ÷2 Am-
pere.
If the values detected are lower than those speci-
fied, replace the regulator.
Before carrying out the checks on the regulator
and the corresponding system, it is always good
practice to check that there is continuity between
the black cable and the earthing.
