IGNITER
INSPECTION
1. Disconnect the center high tension lead from the
distributor cap.
2. Hold it with insulated pliers approx. 5—10 mm
(0.20—0.39 in) from a ground.
3. Turn th ignition switch ON.
4. Remove the rubber seal from the igniter connector.
5. Apply battery voltage to terminal A (LR) with a jum-
per wire.
6. Check that a strong blue spark is visible when the
wire is disconnected.
76G05X-019
If no spark is seen, connect a voltmeter between
terminal B (B) and terminal C (YL), and check for
battery voltage.
76G-05X-020
8. Repeat steps 5 and check
that
the voltage changes
to 2—3V.
9.
If
the voltage is not as specified, replace the igniter.
10.
If
the voltage is as specified, check the ignition coil
and high tension lead.
