2. Continuity test - Wikipedia

   en.wikipedia.org/wiki/Continuity_test

   In electronics, a continuity test is the checking of an electric circuit to see if current flows (that it is in fact a complete circuit). A continuity test is performed by placing a small voltage (wired in series with an LED or noise-producing component such as a piezoelectric speaker ) across the chosen path.

3. Alternator - Wikipedia

   en.wikipedia.org/wiki/Alternator

   An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. [2] For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature . [ 3 ]

4. Dielectric withstand test - Wikipedia

   en.wikipedia.org/wiki/Dielectric_withstand_test

   In electrical engineering, a dielectric withstand test (also pressure test, high potential test, hipot test, or insulation test) is an electrical safety test performed on a component or product to determine the effectiveness of its insulation. The test may be between mutually insulated sections of a part, or energized parts and ground.

5. Growler (electrical device) - Wikipedia

   to test series and interpoles (commutating) fields from a DC motor; to determine phasing and polarity in multiwinding armatures; to test rotors in rotating frequency changers, as well as in wound rotors; to test shorts between turns in taped coils before installation into an armature or a stator; as a low voltage isolation transformer

6. Armature (electrical) - Wikipedia

   en.wikipedia.org/wiki/Armature_(electrical)

   A DC armature of a miniature motor (or generator) An example of a triple-T armature A partially-constructed DC armature, showing the (incomplete) windings In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current. [1]

7. Alternator (automotive) - Wikipedia

   en.wikipedia.org/wiki/Alternator_(automotive)

   Alternator (silver) mounted on a V8 engine Alternator voltage regulator (brushes are worn out) An alternator is a type of electric generator used in modern automobiles to charge the battery and to power the electrical system when its engine is running. Until the 1960s, automobiles used DC dynamo generators with commutators.

8. Magneto - Wikipedia

   en.wikipedia.org/wiki/Magneto

   The development of modern rare-earth magnets makes the simple magneto alternator a more practical proposition as a power generator, as these permit a greatly increased field strength. As the magnets are compact and of light weight, they generally form the rotor, so the output windings can be placed on the stator, avoiding the need for brushgear.

9. Load dump - Wikipedia

   en.wikipedia.org/wiki/Load_dump

   If the battery becomes disconnected while it is being charged the load on the alternator suddenly decreases. However, the vehicle's voltage regulator cannot quickly cause the field current to decrease sufficiently, so the alternator continues to generate a large current. This large current causes the voltage on the vehicle bus to increase ...
