Battery, Mounting and Cables - Battery and Cables 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 ha nd 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 an d 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. Th e 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, follow the test procedure described in Section 414-02 Generator and Regulator of this Manual.
Although these tests will not actually test the battery, they will confirm that the generator, regulator and connecting cables are
working correctly and that conseq uently, 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.

Belt tension is achieved by an automatic tensioner; neither the belt nor the tensioner require service apart from checking
the belt wear indicators at each normal service interval.
The minimum service life of the drive belt is 100,000 miles.
Never apply oil to the belt or to the belt tensioner.
Generator - Charging Circuit

Parts List
The main components of the charging system are shown above.
The output from the generator 'B+' main te rminal passes to the battery via the main terminal on the starter motor and then
the power cable to the high power protection module located in the luggage compartment. From this module, a short main
power cable supplies the ba ttery positive terminal.
The return circuit is through the vehicle body and supplementary ground cables.
The high power protection mo dule comprises four fuses, each rated at 250 Amps.
Battery output uses the same power cable as the charging circ uit, to the high power protection module and to the starter
motor main terminal. Two similar cables, but not such a high rating, supply battery power from the high power protection
module to the fuse box in the luggage compartment an d to the fuse boxes at the front of the vehicle.
