Regulator Rectifier For SeaDoo 4-Tec 278001969 278001581 RXP RXT GTX 3D RFI DI

Regulator Rectifier for SeaDoo 4-Tec

This regulator rectifier keeps charging voltage stable on SeaDoo 4-Tec machines, cross-referencing OEM 278001969 and 278001581 so you can match it to your existing part.

Overview

This regulator rectifier converts the magneto AC output to a regulated DC charge for the battery on SeaDoo 4-Tec watercraft. It protects the electrical system from overvoltage while keeping the battery topped up through a full day on the water. A solid pick for riders replacing a failed or weak charging component on RXP, RXT, GTX, 3D, RFI and DI models.

Specs At A Glance

Good To Know

Q: How do I confirm this fits my ski? A: Check the OEM number stamped on your original regulator and compare it to 278001969 or 278001581. Model and year alone may not cover every 4-Tec variant.

Q: What are signs of a failing regulator rectifier? A: A battery that will not stay charged, dimming lights or erratic gauge behavior often point to a bad regulator rectifier. Test charging voltage at the battery before replacing.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
