Machined Aluminium MOSFET Regulator RMS022-105928

Arctic Cat, Can-Am, Ski-Doo, Yamaha, Kawasaki and Honda, 1994-2026

This is the RMSTATOR red machined aluminium MOSFET voltage regulator, part number RMS022-105928, designed for powersports charging systems on Arctic Cat, Can-Am, Ski-Doo, Yamaha, Kawasaki and Honda machines across the 1994 to 2026 model years. The headline benefit is heat dissipation: after ten minutes of use, the billet aluminium heatsink runs 33 per cent cooler than a standard cast regulator housing. Heat is what kills regulators, so a cooler-running housing is the single most useful upgrade you can make to a charging system that has already failed once.

It is a direct replacement with plug-and-play installation, built from higher grade electrical components, with an improved heat sink design and quality that exceeds the OEM equipment. Every unit is factory tested before shipping, and the opposite connector is included in the box because the original harness-side plug is so often the real fault. The unit uses two plugs and five pins in a square 103 mm by 103 mm body, 28 mm high, with 80 mm between the fixation hole centres. Electrically it delivers a minimum charging voltage of 14.5 V plus or minus 0.5 V, a maximum charging current of 50 A / 500 W, an open circuit voltage of 15 V and an operating range from -20 C to 85 C. One application note: 2006-2007 Can-Am Outlander 400 installations are not plug-and-play and require wire splicing and connector conversion. Check the fitment for your machine before ordering.
