Electrical (A6)Pregunta 66 de 120

Technician A says the charging system voltage at the battery with the engine running should typically be around 13.5 to 14.5 volts. Technician B says it should read exactly 12.6 volts while running. Who is correct?

a.Technician A only
b.Both A and B
c.Technician B only
d.Neither A nor B

Explicación

With the engine running, the alternator should raise system voltage to roughly 13.5 to 14.5 volts to charge the battery and run loads. A reading of 12.6 running would indicate the charging system is not working. Technician B describes a resting, not charging, voltage.
