it has a main box, then the primary 30 amp fuse in the starter relay.
you have asked questions here before that show no understanding of mechanicing.
so i suggest you take this bike to some one who knows what they are doing and have them fix the bike. pay for fixing what you have broken.
then offer to apprentice under the mechanic. seriously, you seam enthusiastic but ignorant. apprenticing under some cranky old dude will teach you a lot. Then you will be enthusiastic and skilled, which means you can really get into trouble.
do not worry that you don't know what you are doing yet, that just means that they will not pay you. in my experience at least every cranky old guy is just looking for stupid young bucks to dispense their wisdom upon. (consider old fart wisdom but remember to question it as much of it has become rancid)
after you have apprenticed for a few years you can become a faux wise dude who dispenses wisdom on the internet.
