Something has been shorting out causing the fuse to blow, replacing the fuse has just dragged this on and if you have increased the Amp rating of the fuse thinking that this will help I am afraid not. What has probably happened is that either the switch or relay has now over heated to the point that it has burnt causing the smoke, the flasher relay should be checked first, but the source of the smoke must be found, if it is a loom that has melted and shorted out this will take a qualified tech to rectify, check the relay first and visually inspect the loom around the fuse and relay box for scorching, start here.
