Section 05 ENGINE MANAGEMENT (POWER TEK)
Subsection 01 (OVERVIEW)
Manual Start Models
At cranking, the magneto sends AC current to the
voltage regulator/rectifier that in turn, supplies the
ECM with DC current. The ECM then supplies
critical functions such as the ignition for engine
starting. When engine reaches approximately 800
RPM, the ECM activates the relay that in turn, sup-
plies the electrical loads (lights, accessories etc.).
Electric Start Models
The ECM is directly powered by the battery.
When the start switch is activated, it wakes up
the ECM which activates the ignition and starting
system. When engine reaches approximately 800
RPM, the ECM activates the relay and in turn, it
allows current from the voltage regulator/rectifier
(supplied by the magneto) to go either to supply
the electrical loads (lights, accessories etc.) or to
charge the battery through the relay.
