Report "My son got a Polaris 570 EFi it was given to him but the battery will not stay charged we replaced it and still no luck we were told it needed a new rectofire which when we pulled it off it did need replaced but it still will not stay charged, any one know what we may need or over looking? It will start and run for a little while then the battery drains out of it and we can’t figure it out. Please if any one can help we would appreciate it"
