Electrical Systems

6. uses the rotational speed of the starter motor to move the starter drive gear and engage the flywheel teeth.
8. ignites the air fuel mixture in the combustion chamber.
9. creates ac current and converts it into dc current.
11. delivers the spark to the spark plug.
14. allows current to flow to the battery until desired voltage is reached.
15. uses a solenoid shift fork to move the starter drive gear to engage and rotate the flywheel.

1. used in lower horsepower engines.
2. provides voltage to the rest of the electrical system.
3. stops the flow of current through the coils.
4. allows current to flow in only one direction.
5. device used to increase the low voltage induced in the primary circuit to a high voltage in the secondary circuit.
7. indicates the thermal characteristics of a spark plug.
10. generates the spark that ignites the air fuel mixture.
12. resists heat to stay at optimal temperature.
13. this part prevents arcing or sparking when breaker points open.
