Product Description

A rectifier is a device that converts alternating current (AC) to direct current (DC). The function is to help the car to eliminate clutter interference, stabilize the output voltage, improve the instantaneous discharge capacity of the power system, increase the torque output, speed up the throttle response, prolong the battery life, shorten the starting time of the car engine, and improve the ignition efficiency.

Chrome alloy material, surface anti-oxidation treatment, ceramic hybrid structure, strong and durable.

Replacing 4012748, converting high-voltage unstable alternating current into voltage-stable 12v direct current, protecting battery and vehicle circuit system, reducing load and prolonging vehicle life.

The performance of onboard electrical equipment and other related components will gradually degrade as the rectifier fails, rendering the vehicle inoperable in some cases.

easy install, fixed check engine light and has polaris 500 efi running much smoother.this was the correct fit for the 2011 polaris 500 efi.I'll do a long term review in the future.

This was used on our Polaris Ranger. Prior, the instrument gauges were flickering and the battery light flashing. some youtube videos later, we decided to replace the original voltage rectifier and this seemed to solve the problem. Really easy to swap out. The female connector was a little small, but was able to make it work.

Upgraded my Polaris sportsman, seems to work great. Had to modify the wiring to work with my sportsman quad though.
