Where is the Voltage Regulator Located on an Alternator?
Where is the Voltage Regulator Located on an Alternator?The voltage regulator is the part of the charging system responsible for regulating the current in the alternator field (the spinning rotor driven by the pulley). It keeps track of system voltage and regulates the alternator field current to maintain a target voltage of about 14.5 volts. .u60d262577d343b49928137060620d997 { padding:0px;

Modern automobiles operate on a 12-volt direct current electrical system. A voltage regulator regulates the charging voltage produced by the alternator, keeping it between a specific voltage range to protect the
