Inspection
Ignition Coil
Perform the following measurements. Replace the ignition
coil if the standard values are not met.
(1) Measure the resistance values of the primary and
secondary coils and of the external resistor with a tester.
If the readings are within the standard limits, it follows that
there is no short or open circuit in the ignition coil.
Standard value:
Primary coil resistance value: 1.08 to 1.32 Ω
Secondary coil resistance value: 22.1 to 29.9Ω
Spark Plug Cable/High Tension Cable
(1) Check the caps and covering for cracks.
(2) Measure the resistance values:
Standard value: 16 kΩ/m
High voltage

Installation Service Points
Distributor installation
(1) Turn the crankshaft so that No. 1 cylinder is at top dead
center.
(2) Aligh the distributor housing and gear mating marks.
(3) Shift 1 tooth of gear to meet the pin with the mating mark
of distributor housing as shown in the illustration.
(4) Install the distributor to the engine while aligning mating
of distributor housings (groove) of the distributor’s
installation flange with the center of the distributor
installation stud.
(5) Removes distributor cap and confirms that the rotor
becomes as shown in the illustration.
(6) When the rotor is not in this position, redo from the
operation in step (2).
