ELECTRICAL SYSTEM
7-13
1-/ 2-Cylinder
Magneto
The electrical system consists of a
flywheel
(1)
, coil plate assembly
(2)
, a CD
unit
(3)
and an ignition coil
(4)
. The 1/2 cylinder engines are
comprised of seven basic electrical systems. The following chart
demonstrates not only the differences but the similarities:
*NOTE
Pulser coils are not present in either the 3.5B or 8/9.8
models. 9.9D2 / 15D2/ 18E2 and 25C3 / 30A4 also.
The chart demonstrates that the 2.5/3.5 non-CD engine have
different components, all other engines are all basicaIly similar. The
basic units are described as follows:
Flywheel
Mounted radially inside the flywheel
(1)
are a number of high
performance ferrite magnets. As the flywheel rotates, the magnets
pass in front of the coils (exciter / alternator) to produce voltage in
the coils.
