Fuse
Replacement
1. When replacing a fuse, be sure to replace it with one of
specified capacity.
If a fuse again fails after it has been replaced, the circuit
probably has a short circuit and the wiring should be
checked.
2. Be sure the negative battery terminal is disconnected be-
fore replacing a main fuse (80A).
3. When replacing a pullout fuse, use the fuse puller supplied
in the fuse box cover.

Inspection
Spark test
1. Disconnect the high-tension lead from the distributor.
2. Hold it with insulated pliers 5-l
Omm (0.20-0.39 in) from
a ground.
3. Crank the engine and verify that a strong blue spark is
visible.
4. If there is no spark, disconnect the connector from the igni-
tion coil and check for voltage at the positive (+) terminal
of the connector with the ignition switch in the ON position.
Specification: Battery voltage
5. If there is no voltage, check the main fuse, ignition switch,
and wire harness.
Primary coil winding
1. Use an ohmmeter and measure resistance of the primary
coil winding. If not within specification, replace the coil.
Prlmary coil resistance: 0.81-0.99112 (at 2O*C [88*F])
Secondary coil winding
1. Use an ohmmeter and measure resistance of the secon-
dary coil winding. If not within specification replace the coil.
Secondary coil resistance: lo-18 kQ (at 20°C [68*F])
Insulation of case
1. Use a 500V megger tester to measure the insulation resis-
tance between each terminal and the case.
Speclficatlon: 10 MS1 min.
