This is a brand new charging voltage regulator rectifier, supplied as a direct replacement for the original unit fitted to electric start Ski-Doo Skandic, GSX and GTX 550 machines, as well as the Lynx 6900 and Lynx ST 600, across the 2002 to 2011 model years. It is a plug-and-play, direct fit part that requires no assembly, so it bolts to the original mounting points at 85 mm centre to centre and connects through the original single four-pin plug.
The unit is built with a higher grade of electrical components than the original equipment part, and its quality exceeds the OEM equipment it replaces. Every regulator is tested before it leaves the warehouse. This is an electric start specific part - it is the charging regulator that keeps the battery topped up and holds system voltage steady once the engine is running, and it is not intended for machines without an electric start charging circuit.

Frequently Asked Questions
Does it fit without modification?
Yes. It is plug-and-play and a direct fit. The fixation holes are 85 mm centre to centre, matching the original, and the single four-pin plug is the original pattern. No assembly is required and no wiring changes are needed.
What is included?
One charging voltage regulator rectifier with four wires of 140 mm terminating in the original-pattern four-pin plug. Mounting hardware is not supplied because the original fixings are reused.
How do I tell whether my old regulator has failed?
Measure the voltage at the battery with the engine running. A working charging system should reach at least 14.5 V plus or minus 0.5 V, and the open circuit voltage should remain under 15 V. A battery that goes flat overnight, headlights that dim badly at idle, or a reading above 15 V that cooks the battery all point at the regulator.
Will it work on a Lynx as well as a Ski-Doo?
Yes. The same unit covers the Lynx 6900 and Lynx ST 600 alongside the Ski-Doo Skandic, GSX 550 and GTX 550. Confirm the OEM number on your original regulator against the cross reference table above before ordering.
