Granada L4-140 2.3L VIN A 2-bbl (1982)
COLD CRANKING RATE - A rating for automotive batteries in a 30-sec discharge test; measured in amperes at either 0~F or -20~F.
COLLECTOR - One of three elements or terminals of a transistor, usually where the output signal is taken from.
COMMUTATOR - A slotted metal ring on the end of the rotor of a generator or electric motor. When in contact with stationary brushes, segments of the
commutator conduct electricity to or from the turning rotor.
COMPUTER - A device that takes information, processes it, makes decisions and outputs those decisions.
CONDENSER - See "Capacitor."
CONDUCTOR - A material, normally metallic, that permits easy passage of heat or electricity.
CURRENT - A flow of electricity. Under the Electron Theory, flow is from negative to positive poles. Under the Conventional Theory, flow is from
positive to negative.
CURRENT LIMITING - A function usually done in the electronic control unit that allows B + to be connected to the sensor without short circuiting.
D
DARLINGTON - A two-transistor switch with transistors connected so that their collectors are common and their gains multiplied.
DATA OUTPUT LINK (DOL) - Fuel calculation data from the EEC-IV processor to the electronic trip minder.
DC - Abbreviation for direct current.
DE-ENERGIZED - Having the electric current or energy source turned off.
DIGITAL - A signal that has two states: ON or OFF.
DIGITAL AUDIO DISC SYSTEM - Sound system that incorporates a compact audio disc player. The player picks up audio signals digitally encoded on
the disc through a laser beam.
DIGITAL METER - A meter that uses a numerical display in place of a needle and is usually of the high impedance type.
DIMMER SWITCH - Handor foot-operated switch that turns the high-beam filaments of headlights on or off.
DIODE - Electrical device that permits current to flow in only one direction. Most often used as a component in electronic controls and accessories. Also
converts the output of an alternator from AC to DC.
DIRECT CURRENT (DC) - Electric current flowing in one direction.
DISABLE - A type of microcomputer decision which results in an automotive system being deactivated and not permitted to operate.
DISCHARGE - Term describing the flow of electric current from a battery. Opposite of charge.
DISPLAY - An output device used to display information.
DISTRIBUTOR CAM - A shaft which is geared to the camshaft on the bottom, and has lobes on the top which open and close the breaker points. The
rotor is also mounted on the top of this shaft just past the lobes.
DRIVER - A transistor in the output control area of the ECA that is used to turn on and off various actuators.
DUTY CYCLE SIGNAL - A type of square-wave signal that does not have a constant on and off time.
DURASPARK II - A breakerless, solid state ignition system introduced in 1978. DURASPARK II used a module and coil similar to the earlier Solid
State Ignition (SSI) system except for calibration. This system incorporated an adapter on the distributor to accommodate the large distributor terminal
housing and larger rotor required for use with the higher voltage breakerless system. In addition, spark plug wire diameter was increased to 8 mm and
improved silicone jacketing was incorporated.
E
EARTH - Term referring to a ground.
ECA - Electronic Control Assembly
E-CELL - A cell which deplates material from the anode to the cathode as a current in the microampere range is passed through it. When the anode is
completely deplated, the E-cell becomes open which turns on a three stage transistor to switch a signal output.
