Battery: Description and Operation

The battery has been designed specifically for Jaguar. It provides the high output which is required for this vehicle, but with a substantial saving in weight. It is a low maintenance battery, located on the right hand side of the luggage compartment floor.

The negative (Ground) lead is connected to the vehicle body. The positive lead is connected to a high power protection module; from here power is connected to the starter motor and distributed to other systems on the vehicle.

The high power protection module comprises three fuses, each of 250A capacity. Two fuses are connected in parallel to provide protection for the starter circuit. The third one provides high level protection for fusebox supply circuits.

PDU is unable to diagnose the overall condition of the battery - only that it is present and supplying battery voltage to the system.

To test the battery.


Although these tests will not actually test the battery, they will confirm that the generator, regulator and connecting cables are working correctly and that consequently, the battery may be at fault. Alternatively, the tests may indicate that the fault lies in the generator, regulator or wiring and not in the battery.
