Installation
1. CAUTION: Make sure that the battery negative cable
to the body retaining bolt is not loose and fully tightened.
Torque: 9 Nm
2. NOTE: Make sure that both the positive and negative battery
terminals are correctly located.
To install, reverse the removal procedure.
3. NOTE: This step is only necessary when installing a new
component.
Using the Jaguar approved diagnostic equipment, reset the battery
monitoring system.
4. Refer to: Door Window Motor Initialization (501-11 Glass, Frames and Mechanisms, General Procedures).
5. Enter the audio unit preset radio frequencies.
6. Reset the clock to the correct time.
7. Start the engine and allow to idle until the engine reaches normal
operating temperature.
8. Switch the engine off. www.JagDocs.com

Generator and Regulator - V8 5.0L Petrol/V8 S/C 5.0L Petrol - Generator - Overview
Description and Operation
OVERVIEW
On 5.0L V8 vehicles (naturally aspirated and supercharger), the charging system consists of a 150 Amp output generator and
regulator assembly. The generator and regulator assembly generates electrical power for the vehicle electrical system and
maintains the battery in a charged state.
When the engine is running the generator produces an alternating current, which is converted to a direct current internally. The
output from the generator is controlled by the voltage regulator (located inside the generator) and then supplied to the battery
through the main battery positive cable. The generator is mounted on the front right side of the engine and driven at
approximately 3 times engine speed by the accessory drive belt.

transmits the calculated voltage to the generator and regulator on the LIN bus connection.
The ECM will over-ride the voltage value requested by the battery monitoring system if it detects a fault in the generator and regulator. The ECM also signals the instrument cluster to display a warning message if it detects a fault with the generator and regulator. For additionalinformation refer to Instrument Cluster 413-01.
GENERATOR AND REGULATOR Component Description
The regulator provides a controlled variable voltage output from the generator. Two electrical terminals are provided on the
outer casing of the generator. One terminal supplies the DC (direct current) voltage output from the generator to the battery
positive terminal. The second terminal provides the LIN bus connection between the regulator and the ECM. www.JagDocs.com
