Vm line-to-line voltage Reference values (V rms)
Short-circuit current
•
For a correct detection of the short-cir-
cuit current, a connector must be pre-
pared that generates a downstream
short circuit between the three alterna-
tor cables;
•
Start the engine and with an ammeter
clamp measure each single cable.
•
If there is a significant difference be-
tween the measure of the single cables
(other than 10 A), this means that the
alternator is defective and must be re-
placed.
CAUTION
WITH THE ENGINE HOT THE VALUES RECORDED ARE
ON AVERAGE 2-3 A LESS THAN THOSE DETECTED WITH
THE ENGINE COLD.
WARNING
NEVER KEEP THE ENGINE RUNNING FOR MORE THAN
ONE MINUTE; FAILURE TO DO SO COULD CAUSE SERI-
OUS OVERHEATING DAMAGES TO THE MOTORCYCLE
CIRCUITS.
RPM
RMS DC current (Arms) (average of the 3 stage
currents)
Voltage on battery poles with engine speed always between 3000 - 5000 RPM
•
Start the engine, after about one minute of operating bring the speed to 3000-5000 RPM,
then measure with a tester the voltage at the battery poles that must always be between
13V and 15V. Otherwise, if the correct operation of the alternator has already been checked,
replace the regulator.
CAUTION
PERFORM THE CHECK DESCRIBED ABOVE WITH A BATTERY IN GOOD CONDITION (START
VOLTAGE ABOUT 13V) MAKING SURE THAT THERE ARE NO ELEMENTS IN THE SHORT CIR-
CUIT.
