My brother and I were out riding yesterday and we both have 1995 580 artic cat sleds. We had the wildest thing happen. Within about 10 minutes of each other we blew the fuse to our efi module. After replacing the fuse several times we finally were able to keep the fuse from blowing. We continued on and did not have any other trouble. When I went to shut mine off it took 10 seconds for the engine to kill. I pulled the emergency swith and this did not help either. Any ideas?
