Note:
Regarding vehicles which have magneto
ignition systems (MCDI, magneto transisto-
rized ignition and magneto ignition genera-
tors), the yellow clip A must be connected
to a consumer (e.g. main, tail or stop lights)
and the green clip B must be connected to
earth.
The cylinder selector switch must be set to
position 4 cyl. with a 4-pole pole wheel,
position 6 cyl. with a 6-pole pole wheel.
Ignition system
no ignition distributor, i.e. one
ignition coil per cylinder
(Single Spark Coil = SSC)
no ignition distributor / with
twin spark coil (TSC = one
ignition coil per two cylinders)
no ignition distributor / with single
spark coils (SSC) and camshaft
transmitter (only one ignition spark
in the combustion cycle)
no ignition distributor / with single
spark coils (SSC) and crankshaft
transmitter (one ignition spark
each in the combustion and
emission cycle)
