Checking the CDI unit
NOTE:
Be sure to install the test propeller before
checking the peak voltage.
1. Remove the cover.
2. Connect the digital circuit tester with
peak voltage adapter B to the ignition coil
lead and the ground.
3. Measure the CDI unit output peak volt-
age. If less than specification, measure
the charge coil output peak voltage.
Replace the CDI unit if the output peak
voltage of the charge coil is more than
specification.
Test propeller: 90890-01620
