12V Aluminum Regulator Rectifier For Polaris Genesis & Virage – Replaces 4010648, 4010304

If your Polaris jet ski is having electrical issues, this little box might be the hero you need.

It's a high-quality aluminum regulator rectifier from topcn-autoparts, designed specifically to fit Polaris models like the Genesis and Virage.

It replaces a handful of OEM part numbers, including 4010648, 4010304, and 4010648D.

Basically, it takes the AC power from your stator and converts it to DC to charge your battery, while also regulating the voltage so you don't fry anything.

It's built with a tough aluminum body for heat dissipation, measures about 72x75x20mm, and has two cables (200mm and 120mm).

It's a 12-volt unit, and it comes with a 90-day warranty.

If your ski is hard to start or your battery isn't charging, swapping this out is a solid first step.

Note, it's not a universal part, so double-check it fits your specific model.
