So my sister gave me her old four wheeler for my boys.  I have put new car on it among other things but I cant figure out why the cooling fan isn't working.  I took it off and connected straight to the battery and it works fine, but when I put it back in the bike  it wont work.  Im sure its electrical is there an easy way to check that.

Welcome to Quadcrazy! So that fan should only come on when the engine gets hot enough.  It not supposed to run all the time. 

1. Have you ran it long enough to see if that’s the case ? 

2. It’s meant to turn on by a heat sending sensor that should be screwed into the head someplace.  Should have a single wire connected to it. When the fluid in the head gets hot enough that sensor kicks in and brings the fan on and will stay on even after you turn the bike off until it’s cool.   That could be bad. If your not sure take some pics and post them and we will point it out for you. You can take it out and clean the sending unit also  making sure the head is not clogged up with shit by the sensor.

3. Is there a light for the engine being to hot on the dash anywhere? A high temp light? 

4. lastly have you checked all the fuses and connections for corrosion/dirt and unplugged sprayed contact cleaner and reconnected?

      I have a Yamaha Big Bear 350 and the reverse doesn’t work, it shifts from low to high easily but it won’t go back to reverse. I’m new to this stuff, so I’ll take any help. Any ideas?

      I have a 425 Magnum that idles great but seems to flood out when I rev it up, sputters, backfires a little somtimes. No water in gas, good fuel filter, carb seems to be fine, good working diaphram. Plug change makes no difference whatsoever.

      I need to figure out how to clean/fix or replace my neutral switch assembly On my 2008 Yamaha big bear 400 as generally the neutral light doesn’t come on when it is in neutral. To get it to come on I have to wiggle the foot shifter and hold it in just the right spot.
      I have googled it and can’t find much on the 400’s. I can’t find a service manual online and the parts manual is super vague.
      I think it is in the right side engine cover area, but not certain. 
       Any help would be great. thanks

      It starts and runs Ok but after a while the temp gage lights up and the fan fails to start.  Any suggestions on where to start looking would be helpful.  Thanks
