The starter is located on the right side of the engine (shown here in a four-cylinder engine)
- 1 - terminal 50 wire (from the ignition switch);
- 2 - terminal 30 wire (from battery);
- 3 - wire from the electromagnetic switch to the starter;
- 4 - starter.
When the ignition key is turned to the "Start" position, voltage is supplied to terminal 50 of the electromagnetic switch located at the top of the starter.
As a result, the starting lever moves the starter gear along the steep thread into the toothed ring of the engine flywheel.
When the gear engages, the electromagnetic switch turns on the full battery current coming from terminal 30, and only after the gear enters the grooves, the starter powerfully cranks the engine.
The starter motor and the pinion are connected by a reduction gear. Therefore, the electric motor rotates much faster than the pinion. Due to this, the starter has higher kinetic energy.
If the engine starts, the gear disengages from the flywheel ring gear.
