ON-VEHICLE INSPECTION
Caution:
Do not confuse the positive and negative terminals of the battery.
Do not remove the battery cable while the engine is running.
Do not perform any operations that generate destructive pulse.
Make sure the firm connection without any wrong wiring.
When pulling out the resistive cord, do not pull the cord section.

1. lnspection of the resistive cord
(1) Remove the distributor cap.
(2) Using the circuit tester, measure the resistance of the
resistive cord.
Limit: 25 kR or less cord
2. lnspection of the ignition coil
(1) Measurement of the primary coil resistance
Standard: 1.2 to 1.5 R
(2) Measurement of the secondary coil resistance
Standard: 7.7 to 10.4 kR
3. Measurement of the pickup coil resistance
Standard: 460

Note:
Pickup coil is measured by the total resistance value of the
two serially connected coils, measured at the connector
section.
4. lnspection of the air gap between the signal rotor and the
pickup coil
Standard: 0.2 to 0.4 mm (0.008 to 0.016 in.)
REMOVAL
1. Disconnect the negative terminal of the battery.
2. Disconnect the resistive cords from the spark plugs.
3. Disconnect the two connectors to the distributor.
4. Remove the distributor cap.
