Ignition Coil Removal/Installation
Remove the fuel tank (see Fuel Tank Removal in the Fuel
Disconnect the leads [A] and remove the ignition coil [B]
with spark plug cap [C].
Install the ignition coils. Note the following.
Connect the primary winding leads to the ignition coil ter-
minals as follows:
Black/White and Red leads
Green/Red and Red leads
Ignition Coil Inspection
Measuring arcing distance:
Remove the ignition coil (see Ignition Coil Removal/Instal-
Measure the arcing distance with a suitable commercially
available coil tester [A] to check the condition of the igni-
tion coil [B].
Connect the ignition coil (with the spark plug cap left at-
tached to each end of the spark plug lead) to the tester in
the manner prescribed by the manufacturer and measure
the arcing distance.
Ignition Coil Arcing Distance
8 mm (0.31 in.) or more
To avoid extremely high voltage shocks, do not
touch the coil or lead.
If the distance reading is less than the specified value, the
ignition coil or spark plug cap is defective.
To determine which part is defective, measure the arcing
distance again with the spark plug cap removed from the
If the arcing distance is subnormal as before, the trouble
is with the ignition coil itself. If the arcing distance is now
normal, the trouble is with the spark plug cap.
If the arcing tester is not available, the coil can be checked
for a broken or badly shorted winding with the hand tester.
The hand tester cannot detect layer shorts and shorts
resulting from insulation breakdown under high voltage.
