Bobcat 763 when I first got the machine the fuse for the headlights was blown I replaced it and it worked for a while I let the machine sit for a couple years started it and the lights worked fine shut it off and they didn't work pulled the fuse and it was melted replaced it and they worked shut it off and they didn't turn back on pulled the fuse and it wasn't blown? I didn't pull the bulbs but maybe they're blown?
