Original Piaggio alternator for 50cc Piaggio engines with direct injection (PureJet). The part consists of stator, wiring harness and pick-up. Completely ready to install.

Defects in the alternator are very difficult to check without expensive special tools. "Shot through" CDI-ignition units, regulators, ignition problems or bad battery charge are often caused by defective alternators. The damage is rarely repairable. Usually only a complete exchange can help. OEM number: 638610 replaces 831372 & AP8515072
