I have a 2011 Kawasaki mule model 4010 with gasoline engine.  The cooling fan is not working. I took the front cover off and unplugged the fan and it works fine on a 12 volt battery. The fuse is good also. I am having trouble finding the temp switch.  Most sources say it is on the radiator but there is not one on this model.  Is in on the engine?

Thanks. I may need to replace the thermostat also.

I just found out that this model does have a temp sensor on the engine that sends information to the ECU which turns on fan thru a relay. 

I hope to do some more checking today if rain holds off.

 

Thanks

Fan, fuse and relay is good. I can inject 12 volts at relay and fan works.  The sensor on engine resistance seems ok but voltage is not right. I hooked a 100 ohms resistor in hope that would trick ECU into turning on the fan relay with no luck.

I  need to pull ECU and check  wiring and contacts for corrosion. I have unhooked battery in hopes of resetting computer. Raining now.

If ECU is bad I may just install a toggle switch and run fan that way.  

Now that cooler weather is here the fan will not be coming on much anyway.  I hope there is not another problem lurking around.

      working on a coleman 550 out fitter , had a shit load of codes, coil, injector , and the map sensor for fuel injector replaced all 3 and figured it would start , but no joy have spark (new plug also and inline fuel filter) cleared the codes and still have the engine light , turns over fine but damn thing still will not start, friends daughters were driving it and turned it off to park , and went back to start it and same thing turns over but will not start , with this machine anyone have any ideas as to what the hell , I should be looking for , no plug's unplug checked wires none seem to be pulled apart or broken !

      2013 hisun 700 will not run, cranks fine
      By Mike Jenkins
      I have a 2013 Hisun with a 686 Yamaha engine.
      I purchased it from an individual and it ran fine as long as the battery was full.
      I replaced the stator and now it will not start (run).  It cranks fine, has fuel pressure, but will not fire up.  I replaced the coil, no luck there.
      a technician told me that it was the wrong stator and wants a mint to replace it.
      the wires all plugged in when I installed the stator.

      2020 Tracker 800 sx front end noise
      By Karlibob
      I have a 2020 800 sx with about 16 hours on it.  From day one I have heard a clunking noise from the front end going over bumps.  Has anyone else experienced this?  Also this past weekend while out riding I heard a noise that sounded like the dump bed bounced three or four different times, again has anyone experienced anything like that.  Thanks, gary

      Hisun Sector e1 Battery replacement: any tips?
      By didgeridoo
      Hello, All!  I've decided to replace the traction batteries in my 2018 Sector E1 with a 48V Lithium set. They may be expensive, but I figure the Discovery Dry Cell are, too. I am not looking for the max driving range, as I have never received near the brochured range to begin with, but a good mix of charge/ get work done/ charge is what I am expecting.
      I have settled on the 48V EAGL kit from bigbattery dot com. Each battery pack provides 30Ah. The kit ships with a charger, as well. The packs would be physically connected in parallel (using a busbar) to one another, maintaining the 48V voltage, but together would be able to provide the amp draw the buggy pulls when going up hill or towing a rake (rated 320 max continuous Amps). This is in comparison to the serial connection the eight 6V lead batteries. Each of the EAGL batteries looks to have its own BMS; am I correct in thinking I will have to use their included charger rather than (simply) changing the onboard charger to lithium mode? The chemistry of the pack is LiFe PO4, for what it's worth.  I haven't torn anything apart yet (to diagram), so  I am not sure how the dash will interpret the AMP draw, but the kit I am looking at includes a dash mounted charge indicator.
      If anyone has completed a similar conversion, do you have any tips? Specifically, how did you remove the original batteries, and how did you secure the new ones? I am guessing that almost any change from the stock batteries would involve at least some modifications. Any tips would be appreciated, especially things I may have failed to consider. Thanks!
