ALTERNATOR CHARGE
NOTESCheck in the configuration readings that the alternator type has been configured
correctly.
When the engine has stopped, the value must be constant and greater than 98 %.
With the engine running, the value varies according to the electricity consumption. The
value must not be constant.
Carry out fault finding on the charging circuit.
Disconnect the 2 track connector from the alternator.
With the ignition on, check the presence of + 12 V on track 2 of the alternator.
With the ignition off, check the presence of a voltage below 6 V on track 2 of the alternator.
Repair if necessary.
AFTER REPAIRDeal with any other possible faults.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
