Charging Circuit

Electrical power generated at the alternator flows via two 'T Piece' connectors to the engine bay 'Dirty Feed' stud. It then
flows via the Battery Disconnect Switch (BDS) to the battery positive terminal. Both the alternator and the battery are
earthed via the vehicle body to complete the charging circuit.
The starter motor and the 'jump start terminal' are also fed directly from the charging circuit.
Go to page 18-X-XX for complete power distribution circuit diagram (Circuit Sheet 25).
+12 Volt Distribution
The +12 volt supply comes from the battery to the battery disconnect switch (BDS). Assuming that this switch is not
activated, 12 volt power is then available from C0046-8 on the BDS to all of the clean feed battery studs.
The following clean feeds are then live:
• Boot fuse box clean feed
• Under bonnet fuse box clean feed
• CEM busbars 1, 2, 3 and 4 clean feeds
12V power to all systems and components is then controlled by the CEM and the under bonnet / boot fuse boxes.
