IGNITION SYSTEM
- Troubleshooting
8-143
OPERATION
NOBGHAB
When the ignition switch is turned to "ON",
battery voltage is applied to the ignition coil
primary winding.
As the distributor shaft rotates, the igniter-opens
and closes the circuit repeatedly causing ignition
coil primary winding current to flow through the
ignition coil negative terminal and igniter to
ground, or be interrupted.
This action induces high voltage in the ignition
coil secondary winding. From the ignition coil,
the secondary winding current produced flows
through the distributor and spark plug to ground,
thus causing ignition in each cylinder-

Check distributor.
0. Check power transistor.
l
Check spark plugs.
2) Spark is good
l
Check the ignition timing.
2. Engine idles roughly or stalls
l
Check spark plugs.
l
Check ignition timing.
l
Check ignition coil.
3. Poor acceleration
l
Check ignition timing.
