Red Machined Lithium-Ion Compatible MOSFET Regulator Rectifier
Honda, Kawasaki, Polaris, Suzuki, Triumph and Yamaha · 1994-2026 · Part RMS023-107140
This is a brand new CNC machined MOSFET voltage regulator rectifier designed specifically for machines running a lithium-ion battery. A regulator rectifier does two jobs at once: it converts the alternating current produced by the stator into direct current, and it holds that output at a steady voltage so the battery and the electronics are not overcharged. A lithium battery has a different charging profile to a lead acid one, and this unit is set to an output voltage of 14.1 VDC, plus or minus 0.1 VDC, which is the figure lithium chemistry prefers.
The housing is a red machined aluminium heatsink that runs cooler by 33 percent than a standard cast regulator housing. Heat is what kills regulators, so the combination of MOSFET switching, which wastes far less energy than the older diode design, and a machined heatsink with far more surface area gives the unit a much easier life than the part it replaces. Overheat protection is built in, installation is plug-and-play, and the opposite connector for the main harness side is supplied as standard so you can renew the plug that so often melts or corrodes on an ageing loom.
Important: this regulator works with lithium batteries only. It is not compatible with lead acid or AGM batteries, and it must not be fitted to a machine still running either of those types.

Frequently Asked Questions
Will this fit without modification?
It is a plug-and-play unit with two plugs and five pins. Because it covers a very wide range of machines across six manufacturers, the correct way to confirm fitment is to check the number stamped on your existing regulator against the cross reference table above rather than going by model name alone.
What is included?
The voltage regulator rectifier unit and the opposite connector for the main harness side. Mounting bolts are not included, so re-use the ones from your original unit.
How do I know the old regulator has failed?
A regulator that has broken down usually shows one of two patterns. Undercharging leaves the battery flat and the measured voltage at the terminals close to 12 V with the engine running instead of rising towards 14 V. Overcharging pushes the voltage well above 15 V, boils the battery and blows bulbs. A regulator body that is too hot to touch after a short ride, or connector pins that have discoloured or melted, both point the same way.
Can I use this with my standard lead acid battery?
No. This regulator works with lithium batteries only. Its output is set to 14.1 VDC to suit lithium chemistry, and it is not compatible with lead acid or AGM batteries. If your machine still runs a lead acid or AGM battery, choose a standard regulator instead.
