COIL GROUND CIRCUIT CONTINUITY TEST
1. BROWN/ORANGE wire terminal
Ignition Coil Resistance Tests
NOTE: An ignition coil with good resistance mea-
surements can still be faulty. Voltage leak can oc-
cur at high voltage levels which is not detectable
with an ohmmeter. Replacing the ignition coil may
be necessary as a test.
Primary Winding Resistance Test
Pull back each plastic connector housing enough
to access the metal connectors.
Set the Fluke 115 multimeter (P/N 529 035 868) to
and test the primary winding resistance of both
coils as follows.

COIL PRIMARY WINDING RESISTANCE TEST
If the primary winding resistance is not within
specification, replace the ignition coil.
If the primary winding tests good, test the sec-
ondary winding resistance.
Secondary Winding Resistance Test
Disconnect both spark plug cables from its spark
plug.

1. Outer spark plug cable to front coil
2. Inner spark plug cable to rear coil
Measure the secondary winding resistance of
each coil as follows.

If the secondary winding resistance is not as spec-
ified, remove the spark plug cap and measure its
resistance as per following procedure.
Spark Plug Cap Resistance Test
Hold spark plug wire firmly near spark plug cap and
unscrew the spark plug cap from the cable and the
ignition coil.
Measure resistance through the cap.
