Electrical System and Components
The SMART-SPARK
™
ignition system used on some
models is an advanced version of the CD ignition
system used on other CV engines. Its operation can be
best understood by first understanding the standard
system and how it works. Since both systems will
continue in use, it is advantageous to understand them
both. The operation of the standard system is
explained first then expanded to cover SMART-
SPARK
™.
