I think that's normal because when you unplug the sensor it causes and open and the fan defaults to turns on. If its plugged in and not turning on, my bet would be a faulty sensor or fan breaker.

Yes, but when that senor is unplugged it throws an Fi code on the dash and the fan will work but as soon as I plug it back in the fan stops which causes it to over heat both sensor and breaker have been replaced but it still not working. Relay is also functional.

Could be the ECM, but hopefully not. There's some troubleshooting the dealer would do. You could refer to the manual and check the temp sensor resistance and output voltage. If you say all else is working, that may be the next step. Do you have the service manual? I just uploaded 2102-2014 which is the closest I could find:

Modern ATV's remind me of modern vehicles.  My wife's 2015 Mustang was having power loss at highway speed but would take off normal.  2 days of troubleshooting, no codes thrown, settled on it being a low pressure fuel pump and resigned to taking it to the dealer.  Noticed last night brake lights stayed on.  So I shimmed the brake light switch and fixed the power loss...guess it was triggering pseudo limp mode.

I bring that up to say....modern ATV's are too darn complicated and hard to troubleshoot. :)

      I’m brand new to 4 wheelers and just bought a 1987 Yamaha Moto 4 350. It has good compression and fuel, but no spark. I’ve looked high and low trying to find how to test all the components of the ignition system, but can’t find anything. This has a new CDI box on it, but I suspect it might be the stator. How do I test the stator on this? Any help would be greatly appreciated!

      i just picked this up. was told ran fine but overheating issues led to replacing head gasket and head. has not ran since. he is not a mechanic but helped someone else who he could not get back to finish job, got aggravated and put up for sale. i was thinking timing issues. i have 110-120psi on all 3 cylinders so i think valves are correct. dont know about distributor yet. however i have no spark. i have no power going to ignition coil. tried to follow white wire but gets lost in wire harness. does anyone have a wiring diagram? can anyone tell me what conditions have to be met before starting. motor turns over so i would think all safeties are met but you never know.

      Im aware that this relay needs a positive (+) and a negative (-) to activate the other side. The blue wire is the neutral wire so when in neutral it gets ground. The green wire is from the parking break; when you pull the break in it gets ground (-). however one of those two needs to be neutral so that the positive from kill switch can go to the starter relay. The ground from the starter relay is from the start switch. Which one (neutral or parking break) should have a positive (+) voltage?

      First post here need some help/advice. I bought a 2001 king quad 300, vin number JSAAK43A212111871. I have been trying to do some basic maintenance as it runs but doesn't idle all that well . I want to take out and clean/repair the  carb but when looking for parts it ask for model X Y K1 K2. How do I know which model I have? I have tried some vin decoders but they haven't told me. If anyone could recommend a carb rebuild kit for my quad Id appreciate it. Also any tips on tracking down an owners manual?

      I am having an issue with a hs500. I bought it broken and have been trying to get it running. It seems to be starving for fuel. If I put my hand over the intake it will crank but will not run for very long because I'm not able to get the correct airflow with my hand. The things I have done so far are. Replaced the fuel pump, fuel filter, mass airflow sensor, idle air adjuster, fuel injector, cleaned the throttle body, replaced the ecu, and still the same issue. I notice the injector does not spray when removed from the head. I dont know if that is common. 
       
      I am out of ideas on what to do next. I have removed the fuel line from the injector and it is getting plenty of fuel. If anyone has an idea on what could possibly be the issue I would be happy to try anything at this point.
