IGNITION SYSTEM
Breakerless Ignition System
Ignition System Schematic
(1) Battery. (2) Ignition switch. (3) Coil. (4) Distributor. (5) Spark Plug.
The ignition system has battery (1), ignition switch (2),
coil (3), distributor (4) with inner electronics
circuits and spark plugs (5). The battery and ignition
switch have terminals and closed contacts to permit
battery current flow through the ignition system. These
components must have closed current
connections to complete the operation of the ignition
circuit. Coil (3) and spark plugs (5) are of the standard
type. The ignition coil changes the low voltage current
into high voltage current to make a spark at the gap of
the spark plug. The coil has two windings around a
soft iron core. The primary has a small number of turns
of heavy wire, and the secondary has many thousand
turns of a very fine wire.
The primary winding is on the outside of the secondary
windings.
