IGNITION SYSTEM
Peak voltage
When checking the peak voltage do not
touch any of the connections of the digital
tester lead wires.
If there is no spark or the spark is weak, con-
tinue with the ignition system test.
If a good spark is obtained, the problem is
not with the ignition system, but possibly
with the spark plug(s) or another compo-
nent.
