Checking the pulser coil
1. Measure the pulser coil output peak volt-
age. Replace the pulser coil if below
specification.
WARNING
When checking the peak voltage do not
touch any of the connections of the digital
tester leads.
NOTE:
• Use the peak voltage adaptor with the digi-
tal circuit tester.
• When measuring the peak voltage, set the
selector on the digital circuit tester to the
DC voltage mode
.
Checking the pulser coil air gap
1. Turn the flywheel clockwise to align the
projection of the flywheel with the pulser
coil projection.
2. Measure the gap between both projec-
tions with a thickness gauge
1
. Adjust if
out of specification.
