Cooling fan motor check
To check the efficiency of the fan motors it is necessary
to connect them as indicated in the figure, utilising a
voltmeter and ampmeter.
During the check, the fans must be fed by 12V and this
test can be carried out on a work surface (connecting
a 12V–9Ah battery) or on board the motorcycle.
The voltmeter is to check that the battery feeds the
motor at 12V. When the fan turns at maximum speed
the ampmeter should indicate not more than 5 ampere.
If the motor does not turn, substitute the fan motor unit
with a new one.
To carry out the above-indicated test it is
not necessary to remove the fan motors
from the engine.
RADIATOR GROUP ASSEMBLY
Before reassembling, check the correct rotation of the
fans, the condition of all components and all connec-
tions.
Radiator check and clean
The dirt and extraneous material embedded in the radi-
ators must be removed.
It is recommended to use compressed air for the clean-
ing of the radiator.
Bent fins can be straightened by utilising a small
screwdriver.
Position the electric fans on the upper radiator.
Position electric fan wiring as indicated in the figure.
