Exam 19: Charging Systems

Most newer vehicles do not have a separate voltage regulator and control the output of the charging system through the ____________________.

Which type of stator winding produces high AC generator charging voltage at low speeds?

A voltage drop over _____ volt(s)indicates high resistance in either the circuit or ground wiring of the charging system.

A whining noise from a malfunctioning AC generator may be caused by a bad ____________________.

Late model vehicles with PCM-controlled AC generators can generate more engine power than earlier models.

Which of the following is NOT a way to increase the amount of voltage induced in an AC generator?

Cooling is required in an AC generator to maintain the temperature of the _____.

An AC generator cannot be liquid-cooled.

Technician A says the charging system is needed to keep the battery fully charged and recharge the battery after starting. Technician B say the charging system supplies all the vehicle's electrical current needs after the engine starts. Who is correct?

What are the four types of charging system failure warning systems?

The alternating current produced by the AC generator is rectified into DC (direct current)through the use of ____________________.

Identify four internal problems of faulty AC generators.

Most AC generator stators use three windings to generate the required amperage output.

Most late model vehicles use a PCM instead of a separate voltage regulator.

All AC generators use an internal fan to move air across the components for cooling.

Hybrid vehicles are being discussed. Technician A says some hybrid vehicles use a motor/generator that is connected to the crankshaft by a drive belt. Technician B says the motor/generator on a hybrid vehicle is located at the flywheel. Who is correct?

Technician A uses a current output test to check AC generator output. Technician B uses a voltage output test to check output. Who is correct?

If the field of a 100 amp, pulse width modulated AC generator [PCM controlled] is fed a 30% duty cycle, how much current will be produced at the generator output terminal?

With no electrical load, charging voltage during a voltage output test should be approximately ____________________ volts higher than during an open circuit voltage test.

Circuit resistance is checked by connecting a(n)____________________ to the positive battery terminal and the output, or battery terminal of the AC generator.
