I have a 2018 Polaris 450 and it has been a great machine but I went out to start it yesterday and nothing. The battery show full charge. The one thing it did notice is that the brake handle closed without much resistance. I opened up the reservoir and it was basically empty. Will this cause starting issues and if I fill and bleed the brakes will this fix the issue? It won't start with the foot brake engaged either. Is there a brake sensor that won't allow starting unless it is engaged?
