CAUTION:
to avoid destroying the power transistor in the igniter.
(c)

Voltage:
If there is a problem, replace the igniter.

INSPECTION OF HA
1. INSPECT AIR GAP
Using a feeler gauge, measure the gap between the signal
rotor and the pick-up coil projection.
Air gap:
2. INSPECT PICK-UP COIL
Using an ohmmeter, measure the resistance of the pick-up
coil.
Pickup coil resistance:
If the resistance is not correct, replace the pick-up coil and
the breaker assembly.
3. INSPECT VACUUM ADVANCE
(a)
(b)
If the vacuum advance does not work, repair or replace as
necessary.
Using a dry cell battery (1.5 V), connect the positive
(+) pole of the battery to the pink wire terminal and
the negative (-) pole to the white wire terminal.
Do not apply voltage more than 5 seconds
Using a voltmeter, connect the positive (+) probé to
the negative (-) terminal of the ignition coil, and the
negative (-) probé to the body ground.
Check the voltage reading.
3A-C (ex. Canadá 4 W D Wagón M/T)
5 V - Less than battery voltage
Others 0 - 3 V
0.2 - 0.4 mm (0.008 - 0.016 in.)
130 — 190 Í2
Disconnect the vacuum hose and connect a vacuum
pump to the diaphragms.
Apply vacuum and check that the vacuum advance
moves.
