The 1993 – 1994 Jaguar XJ6 charging system includes the alternator, an internal voltage regulator, a charge indicator light, load dump module, the battery, an ignition ON relay, an in-line fuse and the wiring between all the components. The charging system supplies electrical power for the ignition system, the lights, the radio, etc. The alternator is driven by a drivebelt at the front of the engine. Below schematic shows the Jaguar XJ6 typical Charging System Circuit. The volt regulator limit the alternator’s voltage to a preset value. This prevents power surges, circuit overloads during peak voltage output.
