I have a 1999 Sabre 1438 that I bought second hand and it was working fine for the first couple months. Just the last couple times I mowed it started first turn of the key, but sometimes had issues re-starting after I had used it for a while. Today i went to use it and it won't start at all. The issue is it won't even turn over. I did find the 15A fuse under the seat is blown. I can't find the exact wiring diagram, but it seems from others I've seen that fuse is between the battery and the key switch. Doesn't explain why it would start sometimes, but not others, unless the fuse was only partially blown and intermittently making contact. Does anyone have ideas beyond the fuse if that's not the only issue. I'm going to replace it and we'll see, but wanted to start my follow up troubleshooting now. Thanks.
