regulator / rectifier 3-pin for Aprilia Amico 90-91, MX, RS, RX, Tuono RX 50 -2005, Rieju 37339 fitting for Aprilia RS Replica 50 PG000 1999-2001,

Rectifier / voltage regulator integrated indicator relay (6 lines) for Derbi Senda X-treme. The rectifier and regulator changes the AC voltage generated in the alternator in the vehicle electrical system used in the DC voltage of 12V and holds the voltage within a certain tolerance range. This means the battery is charged and makes sure that, for example, light bulbs do not burn out. Since this component is subjected to very strong temperature stresses, it breaks often. If the rectifier and regulator are defective, the battery is constantly empty and ignition systems do not function, lights burn through or headlights flicker.
