Miscellaneous Controls: Alternator

NOTE: Although not considered true engine performance-related systems, some controlled devices may affect driveability if they malfunction.

Chrysler Motors passenger cars use either a Nippondenso or a Bosch alternator. The 3.3L and 3.8L engines use Nippondenso alternators. The 2.2L, 2.5L and 3.0L engines may be equipped with either a Bosch or Nippondenso alternator.

The alternator consists of a rotor, stator, rectifiers, front and rear covers and drive pulley. On all vehicles, voltage regulation is controlled by the Single Board Engine Controller (SBEC).

Alternator diodes convert AC current to DC current. The SBEC monitors critical input and output of the charging system, making sure it is working properly.

The SBEC will store in memory any failures within the monitored circuits. The SBEC will translate a failure in the form of fault codes when on-board diagnostics are entered.
