IGNITION COIL PRIMARY PEAK VOLTAGE
Inspect each ignition coil primary peak voltage in the following
procedure.
• Connect the multi-circuit tester with peak voltage adaptor as
follows.
#1 ignition coil:
+
Probe: Yellow lead wire terminal
-
Probe: Ground
#2 ignition coil:
+
Probe: Green lead wire terminal
-
Probe: Ground
NOTE:
Do not disconnect the ignition coil primary wire coupler.

• Check the ignition coil/plug cap for resistance in both primary
and secondary coils. If the resistance is not within the stan-
dard range, replace the ignition coil/plug cap with a new one.
