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 218
Ω
± 10% at 20°C.
Insulation test: ensure that the ohmeter needle doesn’t move while plaing one
x lead to the groove.
Pick-up coil test
Place tester leads between the pick-up output wires in order to determine the
resistance and insulation.
Resistance value: 117
Ω
± 10% at 20°C.
Insulation test: ensure that the ohmmeter needle doesn’t move while placing
one lead to the ground (fig. 3).
