Voltage Regulator Rectifier for Arctic Cat Bearcat, F 570, T 570 and Lynx 2000
Arctic Cat Bearcat 570, Bearcat 2000, F 570, T 570 and Lynx 2000, 2008-2020 - replaces OEM 0630-230 and 0630-321 - part number RMS020-104939
On a snowmobile the charging system is not a convenience, it is a safety item. The regulator rectifier converts the alternating current from the stator into the direct current the machine runs on, and holds that output at a stable voltage so the battery, lights, gauges, handlebar and thumb warmers all behave predictably. It is also a component that lives a hard life - repeated cold starts, heavy accessory loads and constant vibration. When one fails, the machine usually gives clear warning: a battery that goes flat between outings, headlights that surge and fade with engine speed, hand warmers that lose their heat, or a battery that runs hot and gasses because the unit is overcharging it.
This is a brand new aftermarket voltage regulator rectifier and a direct replacement for the original unit, cross-referenced to Arctic Cat part numbers 0630-230 and 0630-321. It is plug-and-play and a direct fit with easy installation and no assembly required, and it is built with a higher grade of electrical components, an improved heat sink and improved charging capability, to a quality that exceeds the OEM equipment. All units are tested before they are shipped. The body measures 78 mm long by 85 mm wide by 35 mm high, with mounting holes 95 mm apart centre to centre and 150 mm wire tails, so it goes into the standard position and connects to the existing harness without modification.

Frequently Asked Questions
Does it fit without modification?
Yes. It is a direct replacement for the original unit - plug-and-play, direct fit, easy installation, no assembly required. It uses two plugs with five pins and five wires on 150 mm tails, and the mounting holes are 95 mm apart centre to centre. Confirm that the number on your existing unit is 0630-230 or 0630-321 before ordering.
What is included?
The RMS020-104939 voltage regulator rectifier itself, tested before dispatch. It connects to the sled's existing harness plugs, so no adapters or extra wiring are supplied or required to fit it.
How do I tell whether the old regulator rectifier has failed?
Measure DC voltage across the battery with the engine running. A healthy system sits around 14.5 V, within about half a volt. Well below that means the machine is not charging and the battery will keep going flat. Above 15 V means it is overcharging, which cooks the battery and can take out bulbs and electronics. Headlights that brighten and dim with engine speed, hand warmers that never get properly hot, or a discoloured and melted connector at the regulator are all strong indicators.
Will it cope with cold-weather use and accessories?
It is rated for continuous operation from -20 C to 85 C and handles up to 50 A / 500 W of charging current, well beyond a standard 570 charging system, which leaves useful headroom for hand and thumb warmers, auxiliary lighting and heated gear. The improved heat sink also helps it shed heat when the machine is working hard and airflow through the engine bay is limited.
