Ducati Diavel Service Manual: Rectifier-regulator

The rectifier (1) is placed in the electrical components compartment.

The rectifier/regulator consists of an aluminium casing containing the diodes that rectify the current produced by the alternator. It also contains an electronic device that regulates the current supplied by the alternator in accordance with battery voltage.

If the battery is drained, the current has the value necessary to restore optimum operating conditions of the battery. In contrast, if the battery is fully charged, the current value will be lower.

Note

Control the charger current by using the dds diagnosis instrument (sect. 6 - 11, Diagnostic instruments).

Removal of the regulator


Undo the two fixing screws (1) of the voltage regulator (2) and remove it together with them.

Important

Do not disconnect the battery cables when engine is running because this would cause irreparable damage to the regulator.
