INSTALLATION
Note
After installing the distributor, adjust the ig-
nition timing (Refer to 5—11).
1. Apply engine oil to the O-ring and driven gear.

Note
Gear driven type, check that the No.1 cylin-
der is at top dead center and aline the distrib-
utor matching marks.

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.

Caution
a) Be sure the battery connections are not
reversed, because this will damage the rec-
tifier.
b) Do not use high-voltage testers such as a
megger, because they will damage the rec-
tifier.
c) Remember that battery voltage is always
applied to the alternator B terminal.
d) Do not ground the L terminal while the en-
gine is running.
e) Do not start the engine while the connec-
tor is disconnected from the L and S ter-
minals.
