B + - Abbreviation for the positive side of the power source.
BASE - One of three elements or terminals of a transistor, usually where an input signal is applied.
BATTERY - A device which converts chemical energy into electrical energy. A group of complete electrical cells assembled in one housing or case.
BATTERY ACID - A solution of sulfuric acid used as the electrolyte in automotive storage batteries.
BENDIX DRIVE - A starter drive system design used to engage the starter motor shaft with the gear teeth on the flywheel. Disengages automatically
when the engine starts.
BIAS - Term used to indicate a certain voltage operating position or range.
BINARY - A number system using two digits - 0 and 1.
BLOCK DIAGRAM - A simplified schematic diagram made up of boxes labeled with the circuit functions.
BRUSH - A pad of electrically conductive material that bears on the commutator to provide an electrical circuit between rotating and stationary
components. See also "commutator"
BULB OUTAGE MODULE - Module used on the Merkur Scorpio which controls the lamp out warning system.
C
CAPACITIVE DISCHARGE - Ignition system in which primary power is stored in a capacitor; ignition spark is created by discharge of the capacitor.
Also called "capacitor discharge."
CAPACITOR - Electrical storage component also known as a "condensor" which acts as an electrical sponge. Wired across the distributor's breaker
points, a capacitor absorbs electricity when points open, discharges it when they close. Capacitors are also used to suppress radio interference.
CATHODE - Negative pole of an electric current.
CHARGE (or Recharge) - Passing an electrical current through a battery to restore it to its proper energy level.
CHIP - A miniaturized electronic circuit etched into a base of silicon.
CIRCUIT - A system through which electricity flows before it returns to its source (thus having completed a circuit).
CIRCUIT BREAKER
CIRCUIT BREAKER - A mechanical device that opens contacts when an electric flow is excessive; used in place of a fuse. When current flow returns to
normal, the circuit breaker in a car closes.
CLOCK SIGNAL - Continuous series of pulses at a constant frequency.
CLOSED CIRCUIT - A circuit which is uninterrupted from the current source and back to the current source.
CLOSED LOOP - A system that feeds back its output to the input side of electronic control assembly which monitors the output and makes corrections
as necessary.
COAST - A speed control operating mode where the system is deactivated to reduce speed by pressing the COAST button. Once the COAST button is
released, speed control is set at the speed that the vehicle is currently travelling. If the vehicle speed is reduced below approximately 30 mph (48 km/h),
the operator must manually increase the speed and reset the system.
COIL - An assembly of two wire coils in a transformer that steps up low-voltage current to the high levels needed to produce an ignition spark.
COIL SECONDARY - Refer to "Secondary Circuit".
