ATLANTIC 300 i.e.
ALTERNATOR NO-LOAD OPERATION CHECK
•
Disconnect the voltage regulator con-
nector «1».
•
Start the engine and take it to 5000 rpm
(throttle grip twisted approximately 1/4
of its travel).
•
With the pocket tester measure voltage
(alternating current) alternately among
the three yellow cables. If the value in-
dicated by the tester is below 50V, the
alternator is faulty.
ALTERNATOR CONTINUITY CHECK
With engine off:
•
Disconnect the voltage regulator con-
nector «1».
•
With a pocket tester, check the con-
tinuity between the yellow cables com-
ing from the stator.
•
Also check the stator support insula-
tion.
Electric characteristic
Standard resistance value:
0.1 - 1 Ohm.
Standard resistance value between the cables
and the stator support:
endless
Voltage regulator check
•
Remove the tail fairing.
•
Disconnect the voltage regulator con-
nector «1».
•
Undo and remove the two screws «2».
•
Remove the voltage regulator.
•
With a pocket tester, check the re-
charge voltage of the black and the red/
orange cables.
