rated voltage: The rated voltage of an engine

generator set is the voltage at which it is designed

to operate.

rear bearing carrier: The casting which houses the

rotor bearing which supports the rotor shaft.

rectier: An electrical component that converts AC

to DC by allowing the current to ow in only one

direction.

regulator/rectier: An electrical component that

contains one or more diodes and a zener diode.

relay: An electrically operated switch usually used in

control circuits and whose contacts are considered

low amperage, compared to a contactor.

reserve capacity: The amount of time a battery can

produce 25A at 80 F (26 degrees C).

resistance (R): The opposition to the ow of

electrons.

resistive load: An applied load that reduces the

possibility of the alternator system delivering full

amperage through the circuit.

rotor: The rotating element of a generator.

secondary winding: A coil in which high voltage is

induced for use at the spark plug.

self-inductance: A magnetic eld created around

a conductor whenever current moves through the

conductor.

series circuit: A circuit having two or more

components connected so that there is only one

path for current ow.

series/parallel circuit: A circuit that contains a

combination of components connected in series and

parallel.

short circuit: An undesirable complete circuit path

that bypasses the intended path and has very little

resistance.

silicon controlled rectier (SCR): A semiconductor

that is normally an open circuit until voltage is

applied, which switches it to the conducting state in

one direction.

single phase: An AC load, or source of power

normally having only two input terminals if a load or

two output terminals if a source.

solenoid: A device that converts electrical energy

into linear motion.

spark gap: The distance from the center electrode

to the ground electrode on the spark plug.

spark plug: A component that isolates the electricity

induced in the secondary windings and directs a

high voltage charge to the spark gap at the tip of the

spark plug.

spark tester: A test tool used to test the condition of

the ignition system on a small engine.

starter motor: An electric motor that drives the

engine ywheel when starting.

starter solenoid: An electrical switch, with internal

contacts opened or closed, using a magnetic eld

produced by a coil.

stator: An electrical component that has a continuous

copper wire (stator winding) wound on separate

stubs exposing the wire to a magnetic eld.

switch: Any component that is designed to start,

stop, or redirect the ow of current in an electrical

circuit.

T – Z

temporary (soft) magnet: A magnet that can only

become magnetic in the presence of an external

magnetic eld.

trigger: A magnetic pick‑up located near the

crankshaft pulley that senses and counts crankshaft

rotation.

troubleshooting: The systematic elimination of

the various parts of a system or process to locate a

malfunctioning part.

vibration mount: A rubber device located between

the engine or generator and the cradle to minimize

vibration.

volt (V): The unit of measure for electrical pressure

difference between two points in a conductor or

device.

voltage: The amount of electrical pressure in a

circuit.

voltage regulator: A component which automatically

maintains proper generator voltage by controlling

the amount of DC exitation to the rotor.

voltage regulation system: A system that controls

the amount of voltage required to charge the battery

with a regulator/rectier.

voltage source: A battery or some other voltage

producing device.
