Arctic Cat 650H1 cat green, the display show a high temp even tho the atv has been sitting all night. Checked the coolant level and it was fine, the fan operates as normal and oil level is within operating level. I also can't figure out why the high beam indicator is also constantly on. I have checked everything from the connections to looking for scraped wires. No luck.

 

Check the plug that goes into the display, clean up the contacts and dielectric grease. I had to replace a temperature sensor on my AC 700 SD Diesel, wasn't very expensive. probably the same sensor.

 

I did check that plug and put dielectric grease and reconnected that plug. I have disconnect the battery and touch the + to the - to de-energize the system. I have disconnected the display for more than 24 hour and reconnect the display. I have followed the step by step procedure of arctic cat tech manual for testing the display. All tests passed per the manual. I just dont understand what is going on with the damn thing.
