Battery System (14.01)
Power Supply (14.00)
May 2007 Workshop Manual 14-1-3
Charging Circuit
Electrical power generated at the alternator flows via two ‘T Pi ece’ 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’ ar e also fed directly from the charging circuit.
Go to page 18-X-XX for complete power dist ribution circuit diagram (Circuit Sheet 25).
+12 Volt Distribution
The +12 volt supply comes from the battery to the battery disc onnect 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.

Alternator and Regulator System (14.02)
Description
The alternator installed to this vehicle is a Denso, SC1, 120
amp rating, with a 14.4 volt regulator.
The Alternator has an 'Altmon' signal that goes to and from
the PCM via a wire in the 3 way connector.
The ‘Altmon’ signal is monitored by the PCM which adjusts
ignition timing and fuelling if necessary to maintain idle
speed when the alternator is charging.
