Cranking, Charging and Electrical Auxiliary Systems
Parts to Know-Page 1
Alternator: An electrical generator or dynamo for producing
alternating current (See generator)
Diode: Solid-state component which permits current to flow
through in one direction.
Fuse: A device designed to open the circuit when a specific
current has been exceeded
Generator: Any machine by which mechanical energy is changed
into electrical energy.
Helix Gear: A gear with inclined plane teeth on the outer part
made to mate with internal gears on a pinion gear.
Ohmmeter: An instrument that has its own source of power and
used to measure resistance in ohms on disconnected electrical
resistors.
`
Overcurrent Protection Device: a device designed to open a
circuit when a specific current has been exceeded. (May be a “one
time” blow fuse or re-setting)
Pinion Gear: A gear with inclined plane teeth on the inner part
made to mate with external gears on a helix gear. It is used on
starters to move inwardly and drive the ring gear of the flywheel.
Rectifier Regulator: A solid-state automatic device used to
rectify AC current to DC currents and to regulate voltage.

Ring Gears: Teeth cut into the outside of a housing or drive unit.
It normally has external teeth and in small engines is found on the
rim of the flywheel.
Starter: A system for rotating the engine to produce compression
and ignition spark for combustion of the air-fuel mixture.
Stator: The part of an alternator or generator’s magnetic structure
that does not rotate.
Voltage Regulator: An automatic device used to regulate voltage
to a battery so the battery will not be overcharged.
