15·8. Ignition Coil and Spark Plug
1. Ignition Coil
1) Removal and Installation
1) Disconnect the battery negative
(-) terminals.
2) Disconnect the wires from the
ignition
coil.
3) Remove ignition coil.
4) To in.taU, reverse the order of
removal.
NOTE:
Be sure to connect the wires to
their proper posftions. Failure to do
so will dam, .. the unit
2) Inspection
Using an accurate tester, inspect the
following items, and replace if defec-
tive.
1) Primary resistance
2) Secondary coil resistance
NOTE:
If the resistance
is
extremely low,
this indicates the presence of a short·
circuit.
3) Insulation between the primary
terminal and case: IOMn or more.
4) If the engine does not run due to
faulty ignition system, check the igni-
tion system as follows:
Check for a cracked distributor
rotor or cap and corroded terminals.
Visually inspect the high tension
wire for condition. Check spark plugs
and adjust gaps as necessary. Replace
the spark plug which is not suitable for
further use.
If the above checks cannot correct
the problem, check the entire ignition
system with an oscilloscope or a cir-
cuit tester in accordance with the
troubleshooting charts at the end of
this chapter.

the centrifugal advancing characteris·
tics by using a distributor tester.
The spark plugs are project type,
having 14 mm (0.551 in) threads and
1.0 - 1.1
rnm (0.039 - 0.043 in) gap.
NOTE:
All spark plugs installed on an engiue,
must be of the same heat range.
