Hmmm...did the code stay on, even after a start?

Did you check the voltage across the battery terminals?

Harley's eat voltage regulators due to heat and high output from the alternator and very little consumption.

RZRs have a fairly small alternator and high consumption, so I doubt its heat failure.

But electronics don't last forever. So my thoughts are voltage regulator.

Not much help am I? But I thought I would share a bit of my experience.

if it comes on and goes away and comes back again its starting to go bad but eventually you will have a bigger problem and have to replace the voltage regulator.

 

Mine went on a night ride no lights no power steering had to have a new voltage regulator

 

I'd bet it's the voltage regulator. I just replaced 1 on a buddy's 1k. Went ahead and lengthened the ground and hot wires so I could relocate it to the passenger side and higher up behind the seat. It seems pretty common for them to go bad on the 1k. Where they are mounted stock, the rear tire slings water on it really bad. From what I've read, when they get hot and get water slung on them, it fries it.

 

Been addressed in several threads, here is one http://www.rzrforums.net/rzr-xp-1000/145247-voltage-regulator.html

 

Hmmm...that voltage regulator looks exactly like an H-D voltage regulator. And given the function of the regulator to take AC voltage/current and rectify it to DC voltage an current.

I'd almost bet they are interchangeable. There are a number of companies making regulators for Harleys, they're much less expensive. Hmmm...

Anybody figure out how to test one? On Harleys we would just unplug the voltage regulator from the alternator, and external plug, and check for AC voltage if you were getting 45 to 60 Volts AC, the alternator was working. If you had less than 12V at the battery posts, the regulator died. And you just installed a new one. Used to carry a spare in the saddlebags of my '91 Fatboy.

Having cut one apart years ago, the outer shell, with the fins, is apparently set like a bowl, the electronics are put in the bowl, and its filled with epoxy. So I'm guessing the fins do help dissipate some heat, but as I posted earlier, I think for the regulator to have a long life, it needs to operate at about rated load.

Perhaps that's why the RZR comes with a fairly small alternator, put in a big one, and if you don't add a lot of electrical load, the regulator can't handle the extra current which has to be "released" as heat.

Just thoughts,

I was thinking the same thing I was seeing some for a jetski for 50 bucks new just dont state the amperage tho

wonder

 

Well I have owned 6 Victory motorcycles and haven't had this problem. We are talking about Rzrs here not Harleys. That's another forum. LOL
Anywhoo
Looks like after gearing up for another ride today and starting the rzr up. ( no rain today) , the regulator is shot. I guess I have to take it back to shop again. Not impressed with the 1000 so far. Kinda like a Harley.

 

Mine went out yesterday as well and the transmission case is leaking... at least ill only have to take it back once i guess.

 

Well...I have learned that RZRs are a bit like Harleys...and like helicopters...the vibrate an they eat parts!! Argue with that will ya??

The regulator on a 1000 must be somewhere without a lot of air flow. Saw your pics, but is back in the engine compartment a good spot?

I do like the location on my 2009 800...right in front of the radiator, lots of air flow, not the dirtiest place, and not hard to inspect/replace.

Perhaps move yours up to the front and see if that prevents some of the heat problems? lengthening the wires with crimp on connector shouldn't cause any problems.

Now, I can't claim to be the smartest...I had battery problems, low voltage, so I replaced the regulator. As I'm getting started on the replacement, I go to remove the positive battery cable...ummm...how come the battery cable eyelet isn't over the bolt but sort of pinched between other wires on the bolt??? Beats me, but I did it...so I went ahead with the replacement, but I'd bet the original regulator is good.

Sigh....

 

This may be a dumb question but here goes. What do you mean by "code pop up"? All my 900 does is the engine like comes on and I have to take it in for them to read it. Is there a code reader available?

brhaminator,

I'm not close to my RZR right now...but either your Owners Manual or Service Manual provides instructions on how to read the code, and there is a list of the codes. This forum is an excellent source of info on what the codes mean and what to do.

Bobby,

I would bet the RZR 800 and a jetski have about the same rating alternator.

If you have a chance an the $50...I'd give it a try.

The danged things only have perhaps a few bucks in components...so its a huge profit item for Polaris...
