Granada L4-140 2.3L VIN A 2-bbl (1982)
V
VACUUM DUMP VALVE - A valve that mechanically releases the vacuum from the servo when the brake pedal is depressed.
VACUUM SOLENOID VALVE - An electrically operated vacuum on and off valve similar in operation to a relay.
VEHICLE SPEED SENSOR - Device mounted on the transmission or speedometer cable that is responsible for monitoring vehicle speed and passing
the information on to the speed control amplifier or EEC IV module.
VOLT - The unit of measurement for the force or pressure of a flow of electricity.
VOLTAGE - The electrical pressure which causes current to flow in a circuit.
VOLTAGE APPLIED - The actual voltage read at a given point in a circuit. It equals the available voltage of the power supply minus the losses in the
circuit up to that point.
VOLTAGE AVAILABLE - The voltage delivered by the power supply (battery, alternator, generator, etc.).
VOLTAGE DIVIDER - Two or more resistances connected in series form a voltage divider network. When current flows the voltage divides itself
across the resistances.
VOLTAGE DROP - A lowering of the voltage in a circuit when resistance, or electrical load, is added.
VOLTAGE REGULATOR - An electrical device that prevents excessive voltage on, or overcharge of, the battery by the generator or alternator.
VOLTMETER - An instrument used to measure the voltage in an electrical circuit.
VOLT-OHM-METER (VOM) - Combination meter used to measure voltage and resistance (ohms). They are available in both analog (measures by
needle movement) or digital (measures by a numeric display). May be referred to as an AVOM (analog) or DVOM (digital).
VREF - Abbreviation for reference voltage.
W
WATT - A measurement of power. One volt multiplied by 1 amp equals 1 watt, and 746 watts equal 1 horsepower. One "kilowatt" equals 1,000 watts.
WIGGLE TEST - Performed with either a voltmeter or star tester while wiggling or tapping the system harness connectors.
WIPER - Refer to "potentiometer."
WIRING HARNESS - A bundle of insulated electrical wires covered by an additional insulating jacket. The individual wires emerge from the harness at
different points to go to various components.
WRITE - A microcomputer operation where information is sent to and stored in memory.
X
X-NOR GATE - A logic circuit that requires both inputs to be the same for a YES output.
X-OR GATE - A logic circuit that requires both inputs to be the same for a NO output.
Z
ZENER DIODE - A two terminal device with 1 PN junction that can conduct in the reverse direction when a certain voltage is reached.
