BS0774 - 12V Rectifier For Engine YX 140 - 150 - 160.

12V Rectifier For Engine YX 140 - 150 - 160.

The BS0774 is a vital 12V voltage regulator/rectifier unit specifically designed to be compatible with YX 140, 150, and 160cc performance engines commonly found in pit bikes and mini-motos. This essential electrical component performs two critical functions: it "rectifies" the alternating current (AC) produced by the engine's stator into direct current (DC) needed to charge the battery and power lights, and it "regulates" that voltage to a stable ~12-14.5 volts, protecting sensitive electronic components from being fried by power surges. A faulty rectifier can lead to a dead battery or, conversely, overcharging and destroying the ignition system. The BS0774 is therefore a key replacement part for maintaining the electrical system's integrity, ensuring reliable starting, consistent lighting, and the overall health of the engine's charging system on these high-performance Chinese horizontal engines.
