Terminology
Concept Description
Current The number of electrically charged particles that flow past a given point on a
circuit in a given time
Ampere (AMP) A measure of current
Volt (V) Measures the difference of the current pressure of a circuit. Core refers to the 2
most common global voltages as:
• 110V (or 110VAC)
• 220V (or 220VAC)
Watt (W) The rate at which an electrical device consumes energy
Resistance The ability of a part to dissipate passing current into heat to lower a voltage.
Resistance is measured in Ohm’s (Ω). All components have a resistance.
Potentiometer (POT) An electronic component which has an adjustable resistance
Hot Wire Delivers power to the unit. Typically has black, brown, or red insulation
Neutral Wire Once electricity has done its work, it goes back through the neutral wire to
complete the circuit. Typically has white or blue insulation
Ground Wire In addition to the neutral wire, the ground wire offers current another path
should an electrical short happen. Also help to dissipate static build-up from
components. Typically has green insulation (may be bare copper in some cases)
General Electricity
Voltages worldwide can vary. Core products are designed to be stable within most voltages:
• For 110V systems the voltage range is: 110 VAC – 125 VAC 50/60hz
• For 220V systems the voltage range is: 190 VAC – 250 VAC 50/60hz
Electrical Tools
Multi-Meter – Used to test voltages, amperages and ohm readings. They can vary on
type from digital (as shown to the right) or analog. For this service manual we will refer
to the digital style for diagnostics.
