Today I went to move my Grizz and when I hit the start button I hear a pop from under the seat and the display goes off for about 5 seconds then comes back on again. I though maybe the battery was weak so I put my charger on it. After about 30 minutes it the charger was off charge and on float. I am still having the same problem. I checked all the fuses and connections. Any advise would be appreciated.
