Turn signals not working, blowing fuse

I didn’t know a bad flasher could blow a fuse

Hey I didn't know the flashers were on a fuse. I have owned '74 and '75 A-bodies. Maybe I knew and forgot. LOL.
Maybe heavier wire to the flasher was used in the early cars. I'd have to look at the diagram. But doesnt really matter as you solved it.
