This kit is designed to convert the Honda XR400R charging system to a true three phase 250W output intended to charge a battery for power electrical accessories such as lights, heated gear, radiator fan, GPS/gauges, and more.

Note that this kit requires custom installation. You must install and mount a battery, DC CDI box, voltage regulator, and wire accordingly.

Battery condition is extremely important. No stator can work correctly with a bad or weak battery. Always fully charge your battery before performing any charging system tests or replacing parts. If there is any doubt, have the battery load tested or replaced.

Brand new aftermarket 250W AC to DC Conversion Battery Charging Kit

This kit is designed to convert the Honda XR400R charging system to a true three phase 250W output intended to charge a battery for powering all of your electrical accessories such as lights, heated gear, radiator fan, GPS, gauges, and more. Not only do you get much more power, but it is available at low RPM on up to redline. No more flickering lights, and easier starting all day long!

We are proud to now offer a complete kit including stator, regulator, and DC CDI Box!

Note that this kit requires custom installation. You must install and mount a battery, DC CDI box and switch, voltage regulator, and wire accordingly.

Read our complete installation instructions

We have even included the opposite connector (main harness side) as we know these are often melted / corroded / defective and a major cause of repetitive electrical issues.

All item pictures are accurate; if in doubt, do not hesitate to compare our item to your original part.

Stator:

  • Direct replacement to your original unit
  • Plug-and-play, direct fit, easy installation
  • Highest grade of lamination materials
  • Highest grade of copper winding, resistant to 200 degrees Celsius
  • Connectors included
  • Pick up pulsar coil included
  • Rubber grommet included

DC Conversion CDI Box:

  • Our PeakRPM CDI Box provides the optimal output for your ride
  • OEM-grade electronic components and printed circuit boards for long-term reliability and performance

Series Voltage Regulator:

SERIES regulators run much cooler than the Shunt and MOSFET voltage regulator rectifier and way much cooler than OEM parts.

  • The regulator is easier to mount because it is smaller than the OEM.
  • Power only flows through the electrical components when the battery is charging.
  • Allows the stator to have lower current flowing when not used, extending its lifetime.

ABOUT THE SERIES VOLTAGE REGULATION TECHNOLOGY

RMSTATOR’s new SERIES voltage regulator brings better reliability and charging system performance. A SERIES regulator is a significant upgrade over typical shunt type voltage regulators.

A shunt regulator controls battery voltage by grounding the stator coils to dissipate current as heat, rather than sending it on to the battery. SERIES regulators control battery voltage by intermittently disconnecting stator coils from the regulator electronics, limiting current flow through the unit and on to the battery completely.

This results in lower regulator and stator temperatures, more accurate voltage regulation, and increased reliability of your charging system components.

Installation

Before installing your new 250W AC to DC Conversion Battery Charging Kit

  • Check the AC output of the stator
  • Replace any burned or corroded connectors on stator and regulator rectifier
  • Check and repair any melted wiring
  • Use hi-temp dielectric grease on all connectors

Our CDI and stator might have a different wire color code than your original part. All the wires are installed in the correct order; please do not change any of the wiring configurations

When bolting stator in, always use locking compound.
If our stator includes a pickup coil, always make sure the air gap is correct upon installation; we suggest as close as possible no less than 0.010".
