I live the middle of nowhere in WA and can't find a mechanic in town who will work on a buddy scooter. So naturally, I am turning to the internet for information

The horn on my 2009 Buddy stopped working a few months ago- nothing happens at all when you push the button. Everything else was still working fine, so I just thought I'd get it fixed if and when I can get the scooter over to Seattle. Today I was driving it and pushing the horn button to see if it would start working, and it started making buzzing sounds and then the blinker also stopped working. When I went to start it after finishing my errands, the starter button also was not working.
When I got home I started looking to see if I could find anything obviously wrong (though I really don't know what I am looking at) and I noticed the fuse was blown. I replaced the fuse, the starter worked again, but then I turned on the blinker and it blew again immediately. I went through 3 fuses this way.
Does anyone have any idea of what could be wrong and/or how to fix it? Is there any way that getting a new battery would help? What about a new black piece that contains the horn and blinker buttons? (and if so, any tips on where to buy that).
Thanks for reading
