Polaris 2014 Ranger Midsize 800 Logo
David Salinas Posted on Jan 08, 2015

I have a polaris ranger 800 midsize, and my coolant fan will not turn on. I replaced the fan relay and still does not turn on and gets hot. How do I know if its the thermistor sensor or is there anoth

I replaced the fan relay switch. I tried unplugging the thermistor sensor what UTV on to see if the fan would turn on, it did not. Only check engine light turns on but the temperature is still be read. I made sure there was enough coolant.

2013 Polaris Ranger 800. How to hookup a starter solenoid in it please?

Question edited for clarity.
Question moved from Cars and Trucks to make model category.

The Solenoid Relay?

This? Test it.

https://www.google.com/search?q=2013+Polaris+Ranger+800+starter+relay

Wiring, these is also a 'Start Diode', not sure what that is about, a diode only lets voltage travel in one direction.

https://www.google.com/search?q=2013+Polaris+Ranger+800+starter+solenoid+wiring

The Polaris forums are a good source of information.

4x4 switch no power fuse good on a 2014 midsize Polaris 800 ranger

If you used a test light to make sure you have no 12 volts to the fuse you have to check the relays near the battery,. The only other spot you can check is the switch it self for 12 volts.. Good luck.

2007 polaris ranger 500 efi 4x4 looses all power before key switch

Check the main fuse to the ignition switch.It will either come directly from the battery + terminal or pick up from the "hot" meaning "positive" side of the starter motor relay. If it comes from the relay you will locate it by following the main "positive" lead from the battery. From the relay you can then trace it to the main fuses. Hope this helps you out.
