ELECTRICAL SYSTEM 14 - 15
3) Start the motor and check the "Indicator"
4) Push the "RESET" button and repeat step 3 twice more.
Results:
a) The "Indicator" light comes on: The power
created by the generator lighting coil
corresponds to the prescribed tolerances.
b) The "Indicator" light does not come on: The
problem is a result of a defect in the generator
lighting coil
.
MEASURING THE RESISTANCE
It is also possible to verify the components of the magneto
system using a digital display ohmmeter.
l
NOTICE:
All measurements must be taken when the parts are at room
temperature (approx. 20
0
C, 68
0
F). Temperature has a
considerable effect on resistance measurements.
Disconnect the connecter near the ignition coil and the magneto.
Measure the resistance between each of the connectors.
Consult the following table to see the resistances and the
colours of the wires.
l
NOTICE:
An ignition coil may be defective in spite of an adequate
resistance reading. A drop in voltage can occur under high
tension, something an ohmmeter cannot detect.
l
NOTICE:
*1
à
The primary coil of the ignition coil cannot be measured
since there is no outside connection.
INSPECTION OF THE VOLTAGE REGULATOR
When lights burn out repeatedly it could mean that the voltage
regulator is defective.
t t
CAUTION
Never have the engine running when the voltage regulator
is defective or when it is not working; the CDI DUCATI
module could be damaged.
