Charging Systems
100
The purpose is to charge the battery and power all the DC components.
What is the purpose of the charging system?
100
This has magnets that spin with the crank.
What is the rotor?
100
a test measured in mA to determine current draw with the key of.
What is parasitic draw?
100
This system uses a 3 wire stator.
What is a 3-phase full wave system?
200
The process of creating current in a conductor without direct contact.
What is magnetic induction?
200
This is a coil of wire wound around an iron core.
What is the stator?
200
This test will give you a reading of .3vdc to .9vdc.
What is forward bias?
200
This system uses 1 diode to convert AC to DC.
What is a single phase/half wave system?
300
The process of converting AC to DC.
What is rectification?
300
This component is usually a solid state device and must be replaced even if half of it tests ok.
What is the regulator/rectifier?
300
The generic spec for this test is 13.5vdc to 15vdc.
What is DC charging voltage test?
300
This system uses brushes and is often called an AC generator.
What is an electromagnetic charging system.
400
What happens when a battery becomes discharged and crystals form on the plates.
What is sulfation?
400
This converts AC to DC.
What is the rectifier?
400
This test is done using an amp clamp with the engine running.
What is max charging output?
400
This system uses 4 diodes to convert AC to DC.
What is a single-phase full wave charging system?
500
A batteries ability to produce amps in 0 degree temperatures.
What are cold cranking amps or CCA?
500
This component produces AC current.
What is the stator?
500
This test is done with the engine running and the stator unplugged.
What is stator output?
500
This system uses magnets that spin around a coil of wire.
What is a permanent magnet charging system?
