2014 Sportsman 400 HO - No Lights

Recommended Posts

Posted (edited)

2014 Polaris Sportsman 400 HO

We had an issue with the lights working on occasion.  Then they just stopped working completely (front and rear). We looked at the EFI fuse and it was melted, but not blown.  We replaced the fuse, but now the ignition will not turn on UNLESS we pull the fuse out...and BTW, the lights still didn't work with the new fuse. Any help would be appreciated. Thanks!

The fact that the fuse melted tells me there's a short somewhere. Do you have a manual with a wiring schematic? Where the fuse melted, start tracing that wiring to see what could have caused it.

I thought the same thing.  However, I found that when I pull the relay out. The lights work fine. Is it  possible it's just a bad relay?

Try this.  Leave the key on and pull the relay. See if the relay clicks when you pull it.  If so then the relay is working.  Or just touch the relay and see if it clicks when you turn the key on.   

What I would do next is trace the wire that feeds the lights and disconnect it. See if that changes anything. Does that bike have a digital screen on it ? Any codes ?

Do what @Frank Angerano mentions, see if the relay is working.

      So Id say about 2 years back I bought a 2013 Polaris Sportsman 500 H.O. off of my uncle. It ran perfectly, nothing wrong at all. I usually go mudding with it or just ride trails with buddies. So as you would assume, the quad is quite dirty from sitting for a few weeks.
       
      STUTTERING PROBLEM: I noticed one day out of nowhere that in high gear at 15-20 MPH, I was already maxed out at 4500-5000 RPM  It would get to 15-20 mph, max out on rpms and start sputtering. It sounded like it was basically acting like it couldn’t go any faster than this.
       
      IDLING PROBLEM: I was fucking with the carberator the other day maybe thinking that is causing my sputtering, and now my idle will shoot up to 2600 on start usually, then I will turn the throttle adjustment down to the normal 1400. The rpms with then fluctuate 10-30 rpms back and forth repeatedly, it will then run for about another 30-60 seconds and the RPMs will slowly drop to about 900-1000 RPM and stall out. I replaced the carburetor and everything seems to be working perfect on that, no leaks and what not but it’s still acting strange. Also, I’ve noticed that when looking into the Electronic Throttle Control that two plates that aren’t supposed to touch have to be WAY past touching to even try to fire up. Even when set at a wide open throttle like that, I still have to give it some throttle to get it to fire up.
       
      Here is what I have done so far: 
      Checked the belt and clutch
      Changed out spark plug (Last one was covered in carbon)
      Cleaned the intake and air box
      Replaced the carburetor
      Replaced the inline fuel filter
      Checked that all lines on carburetor are connected into the right spots
      Checked If intake boot was cracked (Not from what I can see)
      Unhooked and reattached new carburetor (About 4-5 times)
      Cleaned battery terminals and battery off
      Shut on and off Gas Line Cutoff Valve
       
       
       
      My next thoughts are that maybe the TPS is fucked up or maybe the Spark Arrestor is plugged with mud. I was thinking tomorrow to purge the exhaust and also check the ohms output on the TPS.
       
      ANY HELP IS GREATLY APPRECIATED. I HAVE BEEN BATTLING THIS FOR WEEK AND REALLY WANT TO GO RIDING. THANK YOU!

      The rear brakes on this are hydraulic and manual. The hydraulic part is all messed up so I disconnected it all and want to go just manual on the rear. I got it all put back together but doesn't seem to work to well, like not enough pressure. The manual says I should mark the casing before taking it apart which I didn't read until to late. Any ideas? I put new brake pads on.

      I have a 2017 Sportsman 570 SP with a power steering issue. Dealer tells me my machine is one that is not covered by recall and offers no help other than bring it in they will look at it. Any ideas?
