GENERAL INFORMATION
Glossary Of Terms
TOC:
Top dead center. Piston's most outward travel from crankshaft.
Trigger Coil: Pulser coil. Generates the voltage for triggering (closing) the thyristor and timing the spark in COl
systems. Small coil mounted at the top of the stator plate next to the ignition generating coil.
V Regulator: Voltage regulator. Maintains maximum lighting coil output at approx. 14.5 ACV as engine RPM
increases.
Venturi: An area of air constriction. A venturi is used in carburetors to speed up air flow which lowers pressure in venturi
to below atmospheric pressure, causing fuel to be pushed through jets, etc., and into the venturi to be mixed with air and
form a combustible air/fuel mixture.
Volt: The unit of measure for electrical pressure of electromotive force. Measured by a voltmeter in parallel with the
circuit.
Watt: Unit of electrical power. Watts
=
amperes x volts.
waT:
Wide open throttle.
