Replaced bulbs and voltage regulator. I know very little about electrical systems in sled setups, but I imagine they are strikingly similar to that found in passenger. It is also possible your new regulator has gone bad as well. I'd suggest testing the stator for shorts to ground, bad resistance between phases, and output voltage at cruising RPM first. That can all be done by dropping the bash plate. While you are down there, clean and snug the connections to the battery.
Purchased a new rmk 800 2010 model. got it on the snow for the first time a few days ago. All worked fine until there was 1.1 hrs on the meter. All of a sudden the dash went dark, sled started loosing power and eventually shut down. The sled would re-start but, would only stay running for about 30 seconds before shutting down again. 'made for a long trip out' Brought it back to dealer and they discovered that it was a faulty voltage regulator. Has anyone else had this problem with the 2010 polaris d or rmk?
A voltage regulator maintains an even flow of electrical power to an automobile's electrical systems, including the headlights, dashboard components and the stereo. When the parts fail or begin to show symptoms of failing, it can have far-reaching implications to the viability of the automobile. You may notice dimming headlights or unpredictable engine function and even a dead battery. As soon as you notice the symptoms, take the vehicle for an in-depth inspection before the problem leaves you on the side of the road.
Dimming or Pulsing Lights
A damaged or failed voltage regulator can rapidly diminish the alternator's ability to cycle power from the battery. This may cause the vehicle to experience dimming or pulsating external systems, such as headlights and dashboard elements. In addition, the 'check engine' or 'battery' light may appear on the dashboard when the initial failure is detected by the vehicle's on-board computer.
Dead Battery
A burned-out voltage regulator will diminish the vehicle battery's ability to charge or stop it altogether. You will quickly find the vehicle unable to start due to a dead battery. If the battery is recharged, the vehicle will start, although the faulty voltage regulator will only cause the battery to lose power rapidly. In this case, the vehicle should immediately be taken to a mechanic once the battery has been recharged or the car has been jump-started to have the voltage regulator replaced.
Unpredictable Engine Performance
Some aftermarket voltage regulators have experienced problems working in factory-built systems. Engine stalling, sputtering and intermittent acceleration will occur when the vehicle's voltage regulator is unable to handle the power put out by the vehicle's stock (and faster-moving) alternator. This causes the regulator to burn out quickly because it was overworked. Have either a certified mechanic or someone with extensive knowledge of the vehicle being modified look at the aftermarket parts.
