Electric system
Regulator/rectifier
The regulator (2) is fixed to the battery support (3).
The regulator/rectifier unit 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 value will be high enough to restore normal battery operating conditions. In contrast, if the
battery is fully charged, the current value will be lower.
Notes
Check the charging current using the “DDS” tester (Sect. D 5, DDS tester).
Removal of the regulator
Remove the left-hand side fairing (Sect. E 2).
To remove the voltage regulator, first remove the ECU (4) and disconnect the voltage regulator wiring (Sect. M 3).
Undo the screws (1) securing the regulator (2) to the battery support (3).
Remove the regulator (2).
Important
Do not disconnect the battery cables when engine is running because this would cause irreparable damage to the regulator.
