Cranking System Description

Cranking Circuit

The cranking circuit consists of the battery, starting motor, starting motor control relay, engine switch, P position switch (CVT model), clutch switch (M/T model), and related electrical wiring.

Starting Motor Circuit

In the circuit shown in Cranking System Circuit Diagram Cranking System Circuit Diagram
, the coil of the magnetic switch in starting motor is energized when the engine starts. The resulting movement of the plunger and pinion drive lever causes the pinion to engage the drive plate (CVT model) or engine flywheel (M/T model) gear, contact with the magnetic switch ends, and cranking takes place.

When the engine starts, the pinion overrunning clutch protects the armature from excessive speed until the switch is opened, at which time the return spring causes the pinion to disengage.
