Before re-installing the flywheel,

Ignition Armature

1 = Primary connection
2 = Secondary connection
3 = Ground connection
On the ignition armature the primary
and secondary coils are arranged on
the center arm of the iron core and
encased in a plastic compound to
make them moisture-proof. Three
electrical connections emerge from
the coil body, i.e. the primary and
secondary connections and the
ground connection.
There are two ways of testing the
ignition armature:
The resistance of both coil windings
can be checked with the aid of ohm-
meter 5910 850 4800.
Accurate testing is performed with an
ignition coil tester.
