no spark or turn signals kz650b

hello fellow kz riders,

last night i went out for a ride around downtown and on my way back my bike(77 kz650b) just shut off and i had to get it hauled back. after a bit of checking this morning i found out a fuse had blown and replaced all three. right away i noticed the turn signals were not working and after many attempts to start it later realizes i wasnt getting spark. i cleaned some connections and checked a little on the wires, but i wanna see if anyone could point me in a more specific direction before i just start checking every wire individually. also, on a non related question, my number four piston has a bit of a carbon build up whereas the other three do not, would that just be a fuel screw adjustment?

fixed it lol. was a ground wire right in my face haha
