A/C System Testing
Pressure Check
1. Connect the Recovery / Recycling / Recharging unit.
2. Start the engine. Allow to warm up then run at a constant 1,500 rpm.
3. Set the following A/C controls:
• Air Circulation to ‘Recirculate’
• Temperature to ‘Max’ Cold
• Air Flow to ‘Vent’
4. Close all the vehicle doors and windows.
5. Measure the ambient temperature and high / low pressure side reading of Recovery / Recycling /
Recharging unit gauges.
6. Verify that the intersection of the pressure reading of the Recovery / Recycling / Recharging unit gauges and the
ambient temperature is in the shaded zone.
If there is any fault, inspect the refrigerant system according
to the troubleshooting chart.
Performance Test
1. Check the refrigerant pressure.
2. Place a dry-bulb thermometer in the driver-side center ventilator outlet.
3. Start the engine. Allow to warm up then run at a constant 1,500 rpm.
4. Set the A/C unit fan speed to ‘Max Hi’.
5. Turn the A/C system on.
6. Set the following A/C controls: • Air Circulation to ‘Recirculate’
• Temperature to ‘Max’ Cold
• Air Flow to ‘Vent’ 7. Close all the doors and windows.
8. Wait until the A/C output temperature stabilizes.
9. After the blower air is stabilized, read the dry-bulb
thermometer.
10. Verify the ambient temperature.
11. Verify the temperature is in the shaded zone.
If there is any fault, inspect the refrigerant system according
to the troubleshooting chart.
Vacuum Check
1. Stop the vacuum pump, note the high and low pressure side readings of the Recovery / Recycling / Recharging
unit gauges and wait for 5 min.
2. Check the high and low pressure side readings of the Recovery / Recycling / Recharging unit gauges.
1 If the readings have changed, inspect for leaks and go to Evacuation (Refer to ’E vacuation’, page 12-3-10).
2 If the readings have not changed, go to Charging (Refer to ’Charging’, page 12-3-10).
It is recommended th
at a free standing air mover is placed
in front of the conden ser / cooling system.

Leaks
Faults associated with low refrigerant charge weight and low pressure may be caused by leakage. Leaks traced to
mechanical connections may be caused by torque relaxation or joint face contamination. Evidence of oil around such
areas is an indicator of leakage.
Leak Detection
Fluorescent Tracer Dye - A fluorescent tracer dye is incorporated into th e refrigeration system and can be checked for
non-apparent leaks by scanning with a high intensity ultraviolet lamp. The location of leaks can be pinpointed by the bright
yellow glow of the tracer dye.
Automatic Refrigerant Leak Detector - (various manufacturers) Hand-held, portable, battery operated leak detector.
Place in and around A/C system to detect refrigerant leaks.
System Pressure Fault Classification
This table should be used in conjunction with the graphical representations of 'High side' pressure / ambient temperature
and 'Low side' pressure / evaporator temperature. Caution
Observe ALL safety precautions associ ated with ultraviolet equipment.
If erratic or unusual gauge movements occur, check the equipment against known Recovery / Recycling / Recharging unit
gauges.

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.
