(b) Disconnect the high−tension cord at the grommet.
Do not pull on the cord.
NOTICE:
Pulling on or bending the cords may damage the conductor
inside.Do not wipe any of the oil from the grommet after the
high −tension cord is disconnected.
8. INSPECT HIGH−TENSION CORD RESISTANCE
Using an ohmmeter, measure the resistance. Maximum resistance: 25 k Ω per cord
If the resistance is greater than maximum, check the terminals.
If necessary, replace the high −tension cord.
9. RECONNECT HIGH− TENSION CORDS TO DISTRIBU-
TOR CAP AND IGNITION COIL
(a) Assemble the holder and grommet.
HINT:
Connect the high− tension cords to the distributor cap as shown
in the illustration.
(b) Align the spline of the distributor (ignition coil) with the spline of the holder, and push in the cord.

trode gap.
Correct electrode gap: 0.8 mm (0.031 in.)
20. INSTALL SPARK PLUGS
Using a 16 mm plug wrench, install the spark plug. Torque: 20 N·m (200 kgf·cm, 14 ft·lbf)

NOTICE:
”Cold” and ”Hot” in the following sentences express the
temperature of the coils themselves. ”Cold” is from −10° C
(14 °F) to 50° C (122°F) and ”Hot” is from 50 °C (122° F) to
100 °C (212 °F).
22. DISCONNECT IGNITION COIL CONNECTOR
23. DISCONNECT HIGH−TENSION CORD
24. INSPECT PRIMARY COIL RESISTANCE
Using an ohmmeter, measure the resistance between the posi-
tive (+) and negative (−) terminals. Primary coil resistance:
Cold: 0.36 − 0.55 Ω
Hot: 0.45 − 0.65 Ω
If the resistance is not as specified, replace the ignition coil.
25. INSPECT SECONDARY COIL RESISTANCE
Using an ohmmeter, measure the resistance between the posi-
tive (+) and high −tension terminals.
Secondary coil resistance:
Cold: 9.0 − 15.4 kΩ
Hot: 11.4 − 18.1 kΩ
If the resistance is not as specified, replace the ignition coil.
