SPARK PLUG CAP RESISTANCE TEST
If resistance value obtained is not close to value
specified, or cable shows signs of deterioration,
replace spark plug cap, or cable and coil as re-
quired.
Ignition Coil Removal (Front Coil)
Disconnect the spark plug cable.
Pull back the plastic connector housings from both
coil input connectors.
As you hold the top input connector at the wire
crimp with a pair of long nose pliers, quickly heat
the contact end to melt the solder and pull the
connector off the coil terminal.

4. Mounting screws
Repeat the previous step for the second contact.
Remove the two ignition coil mounting screws.
Ignition Coil Removal (Rear Coil)
Cut the locking tie retaining the wires to the igni-
tion coil.
Note the routing of the spark plug cable.
Disconnect the spark plug cable and feed it back
to the ignition coil.

5. Mounting screws
Pull back the plastic connector housings from both
coil input connectors.
As you hold the top input connector at the wire
crimp with a pair of long nose pliers, quickly heat
the contact end to melt the solder and pull the
connector off the coil terminal.
Repeat the previous step for the second contact.
Ignition Coil Installation (Both Coils)
Reverse the removal procedure. However, pay at-
tention to the following.
If the connector housings are too damaged to re-
install, remove them completely and insert heat
shrink tubing before installing and soldering the
small connectors.
Install the BROWN/ORANGE wire on the small
terminal that is on the spark plug cable side of the
coil.
On the rear coil, solder the small wire connectors
on the coil input terminals before mounting the
coil on the frame.
Solder small connectors on coil input terminals us-
ing 60 – 40 flux core solder. Use solder sparingly
and clean soldered terminals using a common flux
cleaner.
