Regulator / rectifier JMP Yamaha YZF-R from year 19, MT from year 20, XSR from year 21 onwards

This article is a cheap alternative to the expensive original spare part.
The regulator corresponds to the original in dimensions, connection and function.

The rectifier or regulator changes the AC voltage generated in the alternator into 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 often breaks down.
If the rectifier or regulator is defective, the battery is constantly empty or, with certain ignition systems, the ignition system no longer works, bulbs burn out continuously or the driving lights flicker.
