This is a used regulator. It has only been run once for test driving. As this is a used item, please understand that it is non-refundable and non-returnable. If the regulator breaks, it can no longer control the voltage, and even if the battery is normal, it will quickly drain or be damaged, shortening its lifespan. It should be compatible with 12V80W3-terminal regulators of the same shape. [Compatibility] Vespa VESPA PX200E PX200FL PX150E PX150FL PX125FL PK50 cosa T5 P200E [Size] Connector: 3 terminals
