My quad was working perfectly, just replaced the CDI. I did a wheelie and came down and stalled, wouldn't start. So I checked the fuse by the battery and it was blown. I replaced the 7 amp fuse with a 7 1/2 amp fuse, because thats what I had at the time. It turned over for a while before I used starter fluid to start it. It started and ran for the 10 minute ride. I shut it off and tried to restart it, the fuse was blown again. Any thoughts?
