So I bought a 2008 Raptor 350 off a guy for $300 he told me all it needed was a new stator. So I bought a new stator and put it in it. When I did that the fourwheeler would start and shut off. I asked a buddy and he said that when you replace the stator you replace the voltage regulator. So I got a new one one and put that in it and it still starts up and shut off when you touch the gas. But if I unplug the voltage regulator it runs good until the fourwheeler gets to a certain RPM then it shuts off. Does anyone know what the problem is??
I just replaced the regulator rectifier on my Arctic Cat 400 with an aftermarket unit from Ebay. The old one had definite signs of burn out. All fuses are proper sizes and there are no cooked wires to be found. Also installed a new charged battery. The regulator rectifier seem to get pretty warm in use...Is that normal, and if not, where should I be looking?
I am having a problem with my 450 es shift, have been going thru the steps in the service manual checking battery, etc. Can anyone please do me a favor and connect a volt meter to your battery, turn on the lights and rev up your engine slowly, my symptoms point to a faulty voltage regulator/rectifier, when I rev my machine up my voltage slowly drops, the higher the rev the lower she goes. mabye triggering an ECM fault, my year machine does not show the fault, you can reset by turning the key off then on and rocking the machine and using the es to shift back to Neutral to restart. I also disconnected the speed sensor and found that the voltage at the Blue/Black wire to GND was 11.25 volts dc, 1 volt less than the battery was showing, according to the manual I should get battery voltage. I have also done a leak test on the battery, 1.5 mA, which is under the 5mA by the manual, disconnected the Voltage reg. and was the same, manaul then says (faulty regulator) not sure if this is my shift problem but would sure appreciate if anyone can confirm the requests above Thanks so much
Charging issues solved with voltage regulator relocation Have you noticed your battery light blinking on your 2008 Poalris RZR? This alarm is telling you that the battery voltage on your RZR is too low. You would think that with a 500W stator that the RZR would have no problem keeping everything running. But even with no accessories and just the factory headlights and cooling fan on, many owners have encountered low voltage issues with their 2008 RZR. One main reason that causes this problem is your voltage regulator. The voltage regulator is designed to automatically maintain a constant voltage level. In doing that work, the regulator will generate heat. Your voltage regulator needs to stay cool to properly charge your battery. 2008 RZRs have a problem with keeping the voltage regulator cool because it is located under the driver's seat. Once the regulator stops working, any power generated from the stator will not reach your electrical system and the battery voltage will drop. Then the battery light on your dash will start blinking and it is just a matter of time before you are stranded. Solve those battery voltage problems on your 2008 RZR without cutting any wires! Our extension allows you to move your voltage regulator from under the seat (no air flow = overheating) to in front of the radiator just like Polaris did on the 2009 models. This is a 10 1/2 foot long extension, using the correct Packard/Delphi connectors and terminals and assembled with correct Packard tooling. The harnesses will be made using high quality Cross Link Polymer wire and covered in high temp, flexible woven loom. This harness allows you to disconnect the voltage regulator on your 2008 Polaris RZR (under driver's seat) and relocate in front of the radiator like you find on 2009 RZRs. November 19, 2008 - Autotrend is currently taking pre-orders for first-run of this harness. Price per unit for this run will be $48.95 plus applicable tax and S&H. If you'd like to reserve a harness, use the email link below or call Autotrend directly. Name, address, phone number and C/C number are required. Credit card will not be charged until harnesses are built. Please note that you will need a bracket to mount the regulator up in front of the radiator as shown in the 2009 RZR photo above. You can order a bracket from your Polaris dealer - Part # - PL5252587.
