Voltage regulators are being discussed. Technician A says charging voltage is decreased when the battery temperature is low because the battery cannot accept high charging rates at low temperatures. Technician B says the voltage regulator increases the current flowing through the field coil when the battery voltage is low. Who is correct?
A)A only
B)B only
C)both A and B
D)neither A nor B

Question

Quizplus · Accepted Answer

Technician B is correct. The voltage regulator increases the current through the field coil to boost the alternator's output when the battery voltage is low. Technician A is incorrect because charging voltage is typically increased at low temperatures to ensure the battery charges effectively.
