regulator / rectifier -101 OCTANE- for Aprilia Derbi Piaggio Vespa 50cc 4T 100cc 4T Ducati

The rectifier/regulator changes the AC voltage generated in the alternator to the DC voltage of 12V used in the vehicle electrical system and keeps the voltage within a certain tolerance range. This charges the battery and ensures that light bulbs, for example, do not burn out.

Since this component is exposed to very high temperature loads, it not infrequently breaks down.
If the rectifier/regulator is defective, the battery is constantly empty, with certain ignition systems the ignition system no longer works, bulbs burn out continuously or the driving lights flicker.
