Really weird. I've not had mine on the ice,yet this year. Hoping I fixed it with the Polaris Starter Relay upgrade. I'm not so sure about what the issue is/was. Like you said, a five ride out on the ice, shut it down and later - no start. I've had two machines that do this - 2010 550 and my 2015 850. They both would start, at some point later in the day. Not so sure it's the same issue with both machines. The 850 might be the brake switch - have to hold the brake to start that machine, at all times.
Here's what I think - a long ride on the ice, with fine mist of ice and snow all through and around the machine. Things are warm and the ice/snow melts, wherever it gets to, then you shut down and it freezes.
Could be the starter, for sure. Last year, I pulled the starter relay and put it back in - instant fix. Maybe coincidental? For sure, not a good feeling when you are out 5 miles on the ice and your machine has tracks and there is not much that will tow you off. If my 850 issue does not get resolved this winter, it'll be the last Polaris, I ever own and it will be gone before next year.
What can I carry to put heat on the starter, while out on the ice. I do carry a jump pack for backup power. Any 12VDC hair dryers out there?
Well, finally got back on the ice. Out yesterday am - 5 mile ride out on bare ice with 10 Deg.F. temps. No snow! Let the machine idle for 10 minutes before shutting down. 5 hours later, NO START! This is with the new Polaris starter relay kit. Only difference was the loudness of the "click". Very audible now. Got my propane torch fired up and holding it some distance from the starter/plastics, was able to get some heat on the starter. Maybe a minute of that and it started just like it should.
So I guess, I'll stop by the dealer to let the tech know my results and then remove and dissemble the starter.
What I really suspect is a typical Polaris issue ---- poor quality control on parts! The other thing that gave me a problem yesterday was the kill switch. One time, I had to switch it back and forth a couple times to get a contact. Strange because I never use that switch. If it continues to be an issue, I'll replace that.
Anyways, an excellent day of fishing.
