AC sine wave: A symmetrical wave form that

contains 360 degrees.

AC voltage test: A test that uses a volt meter to

indicate the voltage potential of the alternator

stator.

alternating current (AC): A ow of electrons that

reverses direction at regular intervals.

alternator: A charging system device that produces

AC voltage and amperage.

amperage: The strength or intensity of an electric

current, measured in amperes (AMPS).

amperes: The measurement of the number of

electrons owing through a conductor per unit of

time.

armature: A rotating part of a DC motor that consists

of wire wound around an armature shaft.

atom: A small unit of a material that consists of

protons, electrons, and neutrons.

automatic switch (circuit breaker, fuse): A switch

that stops the ow of current any time current limits

are reached.

battery: An electrical energy storage device.

battery charge rectier: A component which

changes AC voltage from the battery charge

windings (within the STATOR) to DC voltage. This

voltage could be used to charge a battery.

battery loading device: An electrical test tool

that applies an electrical load to the battery while

measuring amperage and voltage.

breaker point ignition system: An ignition system

that uses a mechanical switch to control timing of

ignition.

breaker points: An ignition system component that

has two points (contact surfaces) that function as a

mechanical switch.

bridge rectier: A device that uses four

interconnected diodes to change one cycle of AC

current into two DC pulses.

brushes: Carbon components, in contact with the

commutator, that carry battery current to operate the

starter motor.

capacitor: An electrical component that stores

voltage.

charging system: A system that replenishes the

electrical power drawn from the battery during

starting and accessory operation.

circuit: A complete path that controls the rate

and direction of electron ow on which voltage is

applied.

circuit breaker, fuse (automatic switch): A switch

that stops the ow of current any time current limits

are reached.

coil: A circular wound wire (winding) consisting of

insulated conductors arranged to produce lines of

magnetic ux.

cold cranking amps (CCA): The number of amps

produced by the battery for 30 sec at 0 degrees F

(‑ 18 degrees C.) while maintaining 1.2 V per cell.

commutator: A sectional piece of copper that is

directly connected to many loops of copper wire in

contact with brushes.

condenser: A capacitor used in an ignition system.

It stores voltage and resists any change in voltage.

conduction: Heat transfer that occurs from atom

to atom when molecules come in direct contact

with each other, and through vibration, when kinetic

energy is passed from atom to atom.

conductor: A material that allows the free ow of

electrons.

contactor: A contactor is an electrically operated

switch usually used in control circuits and whose

contacts are considered high amperage compared

to a relay.

GLOSSARY OF TERMS

In this day of lightning fast communications and an ever increasing level of sophistication in our day to day

activities, the spoken word has become one of the most important tools in our toolboxes. “Word Power” is

the natural extension of your thought processes. Without a high caliber vocabulary, communication with our

peers and/or our customers can be severely hampered. Customers will measure us more than we might

imagine, when we are unable to express our knowledge and expertise accurately and concisely. Exercising

the vocabulary is every bit as important as learning the latest new service procedure.
