When the SCR is triggered or “fires”, up to 200 volts
DC, stored in the capacitor, travels to the spark coil.
Here it is stepped up to as much as 25,000 volts and is
discharged across the electrodes of the spark plug.
(See Figure 49.)
Frequency of change
As needed
Check, clean, and gap Every 50 hours

Ignition timing (when the SCR fires) is also determined
by the flywheel key and the keyways in the flywheel
and crankshaft. Damage to any of these parts will
affect the ignition timing.

CD Pack Operation
The Capacitive Discharge (CD) system (see Figure 47)
is breakerless and contains electronic components that
replace mechanical points and related accessories
(such as a breaker cam, spark advance assembly,
etc.).

A. CD Ignition Module

As the flywheel magnet passes the CD Pack, an AC
voltage is induced into the charge coil. This AC voltage
is converted by a rectifier into a DC signal, which is
then stored in a capacitor. (See Figure 48.)
