STOREDVOLTAGE REGULATION
1.DEF: Voltage too low
2.DEF: Voltage too high
NOTESThe fault is declared present after:
switching on the ignition and waiting 1 minute.
Note:
The on-board network voltage is less than 0.89 times the battery voltage setpoint.
The battery may be used to supply all of the energy. The alternator voltage setpoint is
fixed as soon as the fault appears. Once the fault has been confirmed, the alternator
voltage setpoint is 14.3 V. Regulation resumes as soon as the fault disappears.
Effect on system:
The battery warning light comes on when the fault appears and goes out as soon as
the fault disappears.
Run command AC130 Alternator regulation without any electrical consumers:
–Wait 20 seconds.
–For 10 seconds, the voltage of the alternator (component code 103) should be equal to 15 V +/- 0.2 V at the
battery terminals.
–Wait 20 seconds.
–For 10 seconds, the voltage of the alternator (component code 103) should be equal to 13 V +/- 0.2 V at the
battery terminals.
If the voltages are not correct (see 80A, Battery, and see 16A, Starting charging).
Run command AC130 Alternator regulation without any electrical consumers:
–Wait 20 seconds.
–For 10 seconds the voltage of the alternator (component code 103) should be equal to 15 V + /- 0.2 V at the
terminals of the alternator (between the + terminal of the alternator (component code 103) and the engine
earth).
–Wait 20 seconds.
– For 10 seconds the voltage of the alternator should be equal to 13 V + /- 0.2 V at the terminals of the
alternator (component code 103) (between the + terminal of the alternator (component code 103) and the
engine earth).
If the voltages are not correct, check the conformity of the engine earth.
Check the condition and connection of the 1-track connector of component 103 (tabs bent, oxidised, broken).
Check for + 12 V on connection BPDA of component 103.
Check the continuity and insulation of the following connections:
●Connection code BPDA between components 103 and 163.
●Connection code 2N between components 103 and 645.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the problem is still present, contact the Techline.
AFTER REPAIRCarry out another fault finding check on the system.
