I have a 2017 570 EFI, dealer put a new battery at purchase and it kept going dead. I assumed because it wasn't fully charged and I didn't run it much. Long story short it would go dead while driving. I changed battery, same issue, kept it on a trickle charger, same issue. Tested regulator rectifier, was bad. Replaced with Moffett, was working fine. Took my son for a ride around our yard(fast) the regulator rectifier caught on fire, had to disconnect it to get flames to stop. I got a new one for free, I still have occasional issues while running. Battery hasn't died though. I'm afraid to run it long in hot weather. Was out of warranty period by the time I tested regulator....I think a recall should be issued but I don't know the exact problem. Too many people with same issues.
