Hi all, this is my first post. My XT-1 is 5 years old. I was having trouble starting the unit as I think the battery was near the end of its life. After a few tries of clicking, the tractor would start. It ran fine until I was done. (about an hour) This same scenario happened the last 3 or four times of cutting grass. I was expecting to get a new battery this week. Today, went through the same procedure, it started and I got the grass cut. As I was heading back to the storage shed, the tractor stopped dead. Key turn got nothing. Tried several times and still nothing. Attached my jumper and still got zilch. After looking at things, I realized the battery has a fuse. Checked it out and it was blown. Luckily, I have several more. Put in a new fuse, attempted to start and got nothing. Checked fuse and it was also blown. Put in a higher rated fuse just to see what would happen. It didn't blow but got warm and discolored. Obviously a short somewhere and I have no idea where to start. Suggestions would be appreciated. Thanks.
