Each retard circuit activates when
connected to a switched 12-volt source
and switched “ON.” Many types of
switches can be used such as a dash
mounted toggle switch, a push button
switch on the steering wheel (such
as a nitrous system switch), a switch on
the transmission shifter or an RPM
activated switch. It is not necessary to
switch “OFF” a previous stage for a
succeeding stage to override the previ-
ous stage. When all 12-volt sources for
the retard circuits are switched “OFF,”
the retard circuits revert to normal
ignition timing.
