Description

Starting And Charging Description
The starting system comprises a starter motor and solenoid located at the rear right side of the engine. A starter relay, controlled by the Body Control Unit (BCU), supplies battery power for starter solenoid operation. The starter motor receives its feed directly from the battery.

The charging system comprises an alternator containing a rectifier pack and a regulator to maintain a constant direct current (dc) in the system. The alternator is located at the top right of the engine and is belt driven from the crankshaft pulley.

A warning lamp in the instrument pack illuminates if the charging system is not generating a voltage equal to or more than the battery voltage.

Starting and Charging Supply

Circuit supply
A feed from the battery positive terminal is connected on an R wire to the engine compartment fusebox where it passes through fusible links 1, 8 and 12 and fuses 10 and 13. A feed from the battery is connected directly to the contacts of the main relay located in the engine compartment fusebox.

A second feed from the battery positive terminal is connected on an R wire to the contacts of the starter motor solenoid, located on the starter motor

A feed from fusible link 1 is connected from the fusebox on an N wire to the alternator/generator.

A feed from fusible link 8 is connected on an NW wire to the passenger compartment fusebox and from the fusebox to the ignition switch on an N wire.

A feed from fuse 10 is connected to the contacts of the fuel pump relay located in the engine compartment fusebox The Engine Control Module (ECM) provides an earth path for the fuel pump relay coil which energises and closes the relay contacts.

A feed from fuse 13 is connected from the fusebox to the inertia switch on an NB wire. When the inertia switch contacts are closed, the feed passes through the switch and is connected to the coil of the main relay on a WG wire. An earth connection from the main relay coil is connected on a UR wire to the ECM When the ECM completes the earth path the coil energises and closes the main relay contacts.

Ignition switch supply
With the ignition switch in position II, the feed from fusible link 8 passes through the ignition switch to the passenger compartment fuse box on a Y wire, where it passes through fuse 27 in the fusebox

With the ignition switch in the crank position III, the feed from fusible link 8 passes through the ignition switch to the passenger compartment fusebox on a WR wire, where it passes through fuse 23 in the fusebox.
