Peak voltage

When checking the peak voltage do not touch
any of the connections of the digital tester lead
wires.
NOTE:
S If there is no spark or the spark is weak, contin-
ue with the ignition system test.
S If a good spark is obtained, the problem is not
with the ignition system, but possibly with the
spark plug(s) or another component.
