Alternator Components
This is the rotating component that creates a magnetic field
What is the Rotor
This is the test to perform on a stator winding to verify circuit integrity
What is a resistance test
This alternator winding is commonly used in automotive vehicles and has a capability to provide high output even at low RPMs
What is a Wye Winding
This component is responsible for maintaining stable and controlled voltage to the battery
What is the Voltage Regulator
This type of battery is relatively less expensive and constantly used for cranking and charging systems
What is a Flooded Conventional Battery
This component is responsible for providing the ground to the Alternator
What is the Alternator Housing
This test is performed while running the engine at various RPM while loaded and unloaded with electrical loads
What is an Alternator Output Test
This component could be used to control an generators output
What is a Control Module
This scenario results with a very high voltage over 15 volts at the battery
A Failed Voltage Regulator
This type of battery can be used on RV motor homes or RV trailers that require batteries to be constantly drained and recharged multiple times
What is a Deep Cycle Battery
This component does not move and houses the Windings that create Voltage
What is the Stator
This test is used to allow the alternator to run at maximum potential by disconnecting the voltage regulator on the alternator- But Not Recommended on Newer Equipment
What is a Full Yield Test
This type of circuit voltage is used to Pre-excite a Rotor Winding
What is an Ignition Voltage Circuit
This type of failure can present with interference or static noise coming from the vehicle audio speakers and responsive to RPM
What is a Diode Failure
This is the normal expected battery voltage to be found on an Unloaded Healthy Battery
What is 12.6 Volts
This component allows AC voltage to be converted to DC voltage
What is the Diode Bridge or Rectifier
This type of failure presents with AC voltage escaping the alternator
What is Diode Failure
This lamp will illuminate in the event of possible alternator failure and low battery voltage
What is a Battery Lamp (Alternator Charging Lamp)
This component is responsible for connecting the alternator to the rotating components on the engine
What is a Serpentine Belt
This could present with an unloaded battery voltage of 10.5 volts
What is a Dead Cell
This type of failure presents as a squealing, grinding sound, and abnormal heat buildup on the alternator housing
What is the Rotor Bearing
This type of failure can present with a weakening battery, flickering in the lights or electrical loads responsive to RPM, and low alternator output
What is a stator winding failure
This type of Diode configuration does not waste negative voltage during rectification and instead converts it to positive DC voltage
What is Double Sided Rectification
This Electrical theory is used to control the output of the alternator and requires electrical voltage to be created
What is Electromagnetism
This type of charging is often used for newer model vehicles that do Not supply a constant steady voltage to recharge batteries, instead it will pulsate and fluctuate voltage output to slow charge a battery.
What is the Variable Voltage Regulator System
