Power for the turn signal starts at the flasher, goes up the column through the switch and then back down the column and out the flasher to the lights.
You should have (switched) power on one side of the flasher always. I found in my situation, the fuse block connector at the flasher just plain ol' gave out. My fix was two small "patch cords" with male and female blade connectors. (think two inch long extension cords) I had to find another source for switched power on the block and plug into it with a cord. I removed the flasher from the block, plugged a cord into the "out" socket for the flasher and patched it to the "out" of the flasher unit. I then patched my new source of power to the "in of the flasher. Remember though that you now have a different fuse controlling the turn signals. Yes the flasher is dangling in the breeze, (I secured mine with a zip tie) but until I finally tackle rebuilding my electrics, it works. No cutting was involved, so I feel good about that. Not the prettiest, but it works and again, not permanent but safe.
Be kind. If for no other reason, it will confuse the daylights out of people and make them wonder what you're up to. And ALWAYS drink upstream of the herd!
