AMPERAGE: Describes the strength of an electric current when measured in amperes.

AMPERE (A): Describes a unit of measurement expressing the electrical current flow rate in a circuit. It is determined by dividing the voltage by the resistance.

AMPERE-HOUR: Describes measurement of a battery's ability to deliver a stated amount of current for a stated time. The higher the amp/hr. rating, the more powerful the battery.

AMPERE HOUR CAPACITY: Describes a storage battery's ability to deliver a specified current over a specified length of time.

AMPERE-HOUR METER (Ahm): Describes an instrument designed to monitor and record the product of electrical current and time (ampere-hours) for a given circuit.

ARMATURE: Describes the movable part of a relay system that indicates the presence of electric current.

ARMATURE 2: Describes the portion that revolves between the pole shoes in either a starter or generator made up of wire windings which, when it rotates, causes an electric current to be induced.

ARMATURE BRAKE: Describes a starter component that can be either mechanical or electrical used to disable an armature movement after the starter motor has been switched off.

ARMATURE END PLATE: Describes the endplate of a laminated armature core of sufficient mechanical strength to enable the laminations to be clamped together tightly to prevent vibration.

ARMATURE RELAY: Describes a relay that is electromagnetically operated, causing the armature to be magnetically attracted.

AMPERAGE: Describes the strength of an electric current when measured in amperes.

FUSE: Describes a protective device (usually enclosed in glass or plastic) with a thin wire between two terminals. The wire will break or melt when the current draw exceeds the capacity of the fuse. In this way, the circuit is protected from overload.

GENERATOR: Describes a mechanism that generates power.

CONTINENTAL-TYPE FUSE: Describes a ceramic fuse with conical end caps, colour coded to provide for different values.

FLEXIBLE DRIVE: Describes a drive consisting of a cable held in an outer sheath, used for mainly light applications such as speedometers, rev counters and windshield wipers

FUSE BOX: Describes a container with a removable cover that holds the fuses for the various electrical circuits, which are all routed through it

FUSIBLE LINK: Describes a particular length of smaller gauge wire designed to "blow" if heavy current flows in a circuit.

POLARISING: Describes the process of sending a quick surge of current that will cause the pole shoes to assume the correct polarity, thus ensuring that the generator will cause the current to flow in the same direction as standard.

WATT: Describes the international unit of power measurement where a single watt equals one joule per second.

VOLT: Describes a unit of electrical force capable of moving a current of one ampere through a resistance of one ohm.

VOLTAGE: Describes the difference in electrical potential between one end of a circuit and the other.
