I just picked up a 2008 arctic cat 400 for my wife with 400 miles on it. On the first ride after 5 miles the gauge went blank except for a flashing temp symbol, then the gauge came back on with the temp symbol flashing.Now this happens most the time, even when it hasn't run, so it's not overheating. I've cleaned (I think) all connections. Anybody have any ideas as to what's going on?

 

May need a new temperature sensor. not sure just a thought.
