2004 Late 2004 Sportsman 500 Fan runs with ignition off

Recommended Posts

Hi all,

My Late 2004 Sportsman 500 fan runs with the ignition off and is not running to the normal speed. I had to disconnect the battery to shut off the fan. Looking at the wiring diagram it appears that the SSCB No. 1 is the only possible source of the issue. I assume this is also called the ECM but not possitive.

Has anyone else seen this type of issue and is the SSCB need to be replaced or is there other items like dirty connections that may be the source of the issue.

Thanks!

Craig

Thanks Dakota Demon! The late 2004 model was the first without a standalone relay for fan control and the fan control is part of the "Logic Box" module and since there is no testing procedure to check the module i was hoping that others have experienced the same sort of problem and the Logic Box fixed their issue.

Thanks again for the support!

Craig

      Hi Everyone,
      I am new to this forum and hope that someone out there can help me, I have an early Suzuki King Quad 300 (280cc) which starts intstantly every time but at about half revs or there abouts it starts spluttering and will not rev any higher, this fault is present whether choke is applied or not, some one suggested that silencer maybe be clogged so removed baffle but no improvement have removed carb and stripped 3 times but still no joy.
      Any ideas would be most welcome.
      Cheers Rob

      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!

      Hello. I am a new member as of today. I had a quick question to ask. I recently was driving mt HONDA RANCHER 2004 GPSscape 400 and my display stopped working. I was driving the atv and all of a sudden the speedometer and the service lights went out. Also the lights stopped working. I am still able to shift gears, change from 2wd to 4wd, and can still select if I want EPS or Auto. I have checked my fuse box and have changed a few of them around. It did not change anything. I was wondering if anyone had any idea of what had happend. Thank you for your time- Trenton

      So i was riding the other day and my quad randomly shut off. It started back up and ran completely fine for a little while and then it started idling terribly.
      I cleaned the carb and changed all the jets and everything except the float due to the rebuild kit not coming with one and it actually runs worse then it did before.
      It will run and idle decent now but when I give it gas it dies.
      Does anybody know what could be wrong?
      I also changed the spark plug and air filter along with the oil and oil filter.
