Granada L4-140 2.3L VIN A 2-bbl (1982)
FUEL PUMP MONITOR (FPM) - Input used to monitor the fuel pump secondary circuit.
FUEL PUMP RELAY (FP) - Relay or its control line. Relay is controlled by ECA processor. Supplies power to electric fuel pump of EFI/CFI system.
FUSE - A metal link in a circuit that melts when the current flow is excessive, thereby breaking the circuit.
FUSE BLOCK - An assembly concentrating most or all of a car's fuses at one point.
FUSIBLE LINK - A wire or bar designed to melt if more than a certain amount of electrical current is transmitted through it. Often used as a main fuse
or backup fuse for large sectional portions of a car's electrical system.
G
GAIN - A comparison of an input signal level to an output signal level.
GASSING - The venting of hydrogen bubbles from battery acid as the battery is recharged.
GENERATOR - An electromechanical device that converts mechanical power into direct current electricity.
GLOW PLUG IN CYLINDER HEAD
GLOW PLUG - An assembly that resembles spark plug but with a heating element instead of electrodes. Used at the beginning of the starting cycle in a
diesel engine to aid compression ignition. Sometimes spelled "glo plug"
GND (or Ground) - Common line for all vehicle power, vehicle chassis ground and engine block ground, connected to vehicle battery negative terminal.
GROUND - The negatively charged side of a circuit. A ground can be a wire, the negative side of the battery or even the vehicle chassis. The ground
circuit must be at least the same size or bigger than the positive (hot) wire.
GROUND CIRCUIT - The return side of an electric circuit. Usually the frame, body or engine of a single-wire automotive system.
GROUNDING - Connecting one side of a car's electric circuit to the chassis, body, or engine. These parts then provide a metal path that conducts
electrical current back to the car's battery to complete a circuit. Grounding may be done with a jumper wire.
GROUP - A set of battery plates, either positive or negative, joined together but not assembled with separators.
GROWLER - An electrical device for testing electric motor or generator armatures for shorts.
H
HALF-WAVE - A pulsating DC produced by rectifying AC.
HALL-EFFECT - The "Hall Effect" is a process where current is passed through a small slice of semi-conductor material at the same time as a magnetic
field to produce a small voltage in the semi-conductor.
HARD SOLDER - Uniting two pieces of metal with material having a melting point higher than "soft" solder. Example: silver soldering.
HAZARD WARNING SYSTEM - Electrical switching device and associated lights (usually the front and rear turn-signal lights) producing flashes of
light to indicate that a car is in a distress situation. Also called "emergency flashers" or "fourway flashers".
HEAT RANGE - A classification for spark plugs. The higher the number, the "hotter" the plug runs, which means that the plug does not dissipate heat as
quickly as a "cooler" plug does.
HEAT SINK - Metal bracket in end frame of alternator that contains and absorbs heat from diodes.
HIGH TENSION - Secondary or induced high voltage electrical current. Circuit includes wiring fron. ignition distributor cap to coil and to each spark
