2011 Fan Issue (Circuit Breaker Location Problem)

Searched the forum high and low recently to try to resolve an overheating issue. My main problem being the fan not running at all.

Began by removing air from system by raising front end, removing rad and overflow caps, running to temp and bleeding the system. Proceeded to check fan by running direct to battery and everything worked ok. Then swapped relays and again a no go. Then decided to look at the wire diagram for a fuse, and found that a circuit breaker is in-between the battery and fuse block. Normally they are found under dash, but after further breakdown and searching, mine was about 18" from battery laying between the skid plate and underbody. Of course a perfect area for mud and the last place to dry out, it was completed rusted/corroded.

Below are pictures of one similar and the way I found mine. Rest assured its not going back to where it was on my machine. Now I now a lot of people stay clear of mud/water, but this is still no place for something that can go bad so fast and easily. My machine was built 08/10 and is currently at 27 hrs. Hopefully this may save others, my advice would be to just take a peak under the dash and see if yours is located in a dryer location that mine was.

You guys rock. Had my 2011 RZR back to the dealer TWICE to get this intermittent fan issue fixed. They couldn't figure it out.
Reading the forums and came across this - and yep, mine was completely rusted through.
Thanks for sharing the information! - This forum pays for itself a few times a month! :)
I am running new wiring and moving mine up behind the seat.
Sitting on the skid plate.... What were they thinking!?

Thanks for posting this same on mine and have relocated circuit breaker after my first one completely corroded thru.

So I just pulled my seats out, and sure enough, there's my circuit breaker....rusting away...Def not a water proof part. I'm wondering what to do about this...I've got the extended warranty for 4 years...If I screw with it, and my mod goes bad, engine goes, I'm at fault...If I leave it be, it will fail, while I'm stuck in the middle of some place. ARGH.

How is the circuit breaker attached to the harness? It's wrapped tight into the harness so I can't see w/o tearing it apart.

WTF !!!

Now I got to crawl under mine.

You guys are right... that's the crap the Chinese companies would do. OK... I've seen thermal breakers in the wiring harness... but even if it was waterproof... who was the genius that decided to put it UNDER the RZR.

I feel bad for the guys who put new skid plates on. They will have to take them off to get to it.

As far as I know, the 2011 models were the first ones to do this.
Yes, you have to take off the skid to get to it - mine was taped to the wire loom with electrical tape.
I have the extended three year warranty, and my dealer seemed ok with me relocating it. (They did it for my father in-law after seeing how I did mine)

Shit :( Now I also have to open things for my peace of mind... Sure would like to give the SOB who installed there a bill for my time..

Personally, I would NOT put it behind the seat. This is a $4.00 ckt breaker designed to be in a DRY area. When I wash mine, everything except under the dash gets wet.

I will relocate mine, but it will be under the dash in a dry area.

I think the preferred place for a breaker is as close to the battery as it can be. I put a new one in and relocated it under the seat. It came with a cheap rubber jacket to "waterproof" it then I siliconed the rest of it. Not a problem from it in 4 months.

Hi Guy's here we go,

I have a 2011 RZR S. After reading this thread, I looked under the seat and could see the ckt breaker. I dropped the skid plate on one side and found the breaker taped to the harness like everyone else. The connectors are the push on type. I bought my RZR used, has 3 months of warranty left and was owned by a 60+ year old guy guy who traded it in for a RZR S 4 to haul his grand kids in. So I doubt he did a lot of stream crossing....Heck I'm 69.

The ckt breaker is a 20A protecting a 16g wire.???? It feeds directly off the battery.

I used 14g wire from the battery to the ckt breaker and 14g to the existing 16g wire in the harness. I mounted a small box behind the seat to mount the breaker in.

The breaker was starting to rust/corrode. What a POS of engineering....

In our application they would be called a poor choice for a electrical connection in a wet area.

They could have mounted that breaker next to the starter solenoid where the power comes from and not under the battery compartment.

Like Polaris hired a bunch of engineers from General Motors. Don't get me started........................................

VirtualRider,

The OP indicated his fan quit and had no power to the fan and swapped relays. The fan relay is under the dash. My suspicion is the breaker feeds the relay, since the thermal switch could not supply the needed current to run the fan and just picks the relay.

Would be easy to check. Pull relay, and the breaker, ohm the wire.

I sliced mine, soldered the connection and then used a 4" piece of heat shrink to seal it. Not the junk heat shrink from Radio shack, the good stuff you need a heat gun to shrink. I am comfortable I have a good connection.

Using a butt connector is a bad idea in a wet location.
