CHECKS
The whole ignition system can be tested for eventual malfunctioning or weak
spark. If the electrodes generate a suitable spark, the whole electronic system
works regularly. If there is no spark, carry out the testing of each component
until the problem will be solved.
Follows the troubleshooting schedule until finding the trouble cause.
Ignition coil test
Connect the leads tester to the coil output wires (Pink-Green) in order to
determine the coil resistance and insulation (fig. 1).
Resistance value 150
Ω
± 10% at 20°C.
Insulation test: connect one tester lead to the ground, ensure that the
ohmmeter does not move (fig. 3).
HT Coil test
Remove the petrol tank and seat.
Disconnect the electrical wires and spark plug cap.
Measure the resistance between ignition coil te and -
Standard resistance: 4.0
Ω
±10% at 20°C.
If there is no continuity, replace coil.
Measure the resistance between the electrical wire terminal and the high
tension wire without spark plug cap.
Standard value: 13.8 k
Ω
± 10% at 20°C (fig. 4).
If the ohmic value is very different from the standard value, replace the coil.
