| STEP | CHECK TO BE PERFORMED | REMEDIAL ACTION IF THE CHECK IS NOT OK |
|---|
| 1 | Alternator terminal D+ checkWith the engine running, check that the voltage is more than 5.5 Volts between terminal D+ and earth | Replace regulator Op. 5530A24 ALTERNATOR VOLTAGE REGULATOR - R.R. WITH ALTERNATOR REMOVED If OK replace the alternator Op. 5530A10 ALTERNATOR - R+R |
| 2 | Check the alternator charge with the consumers deactivatedConnect the ammeter pliers EX-02 1000 Ampere to the Examiner diagnostic equipment using the EX01 cable.Position the ammeter pliers so that the positive battery lead passes inside the sensitive ring and the cable being examined is enclosed by the ring.Zero the pliers using the CALIBRATION button on the Examiner.Connect a voltmeter to the battery terminals.Deactivate all the consumers.Start the engine and let it reach 2000 rpmCheck that the voltage is between 14.2 and 14.8 V (at 20°C)Measure the current and check that it is around 3 A ±10% (at 20°C)Check whether the figures are very high or whether there is overloading (excessive escape of electrolyte), whether the voltage regulator is defective or whether the alternator field coil is short circuited to earth | Check that the alternator drive belt tension is correct.If OKReplace regulator Op. 5530A24 ALTERNATOR VOLTAGE REGULATOR - R.R. WITH ALTERNATOR REMOVED If OKReplace alternator Op. 5530A10 ALTERNATOR - R+R |
| 3 | Check the alternator charge with the consumers activated.Activate the dipped headlightsActivate the heated rear windscreenActivate the passenger compartment heater fan at maximum speedStart the engine and let it reach 2000 rpmCheck that the voltage is between 13 and 14 V (at 20°C)Measure the current and check that it is around 36 A ±20% (at 20°C) | Check that the alternator drive belt tension is correct.If OK replace the alternator Op. 5530A10 ALTERNATOR - R+R |
