Fast Flashing Turn Signal after hazard replacement
I had no brake lights and replaced the hazard switch. Now that I have replaced it, I am getting a fast flash on the right side turn signal butt I now have brake lights. All other lights work. Running lights, 4-way, tail lamps brake lamps. Just to see if I had a bad new switch, I reinstalled the old switch and all lights worked except of course the the brake lights. Since I now know that all the lights are working, what is causing the fast flash on the right side with the new hazard switch installed?

Just to be on the safe side before you get yourself deeper into this, did you check your right side front and rear light bulbs to make sure you don't have a blown filament or a bad bulb/socket connection?
You said all your lights work, but it could be that one of your right side "dual" filament light bulbs has a filament blown or has a bad socket contact and you didn't notice before because of the bad hazard flasher.

I put the old hazzard switch in and all work as normal except the brake light as that was why i replaced the hazzard switch in the first place. Turn signals, hazzards, tail lamps etc.

Did you try it with the car running. It's possible the new switch is hyperflashing because the battery is a little low on voltage. I'd expect you got a bad switch if it doesn't work with the engine running.

It is odd. Are you sure the right filament in each bulb is flashing? Bad ground or wiring could cause the low power ~9W running light filament to be flashing instead of the high power ~28W turn/brake filament. The lower load could cause hyperflashing.

Hyperflash
Maybe your old flasher had been replaced by one for LED's, that I don't know.

Well, there's your problem. The flasher used the load to set the flashing speed. It senses load so it can hyperflash with a blown bulb to let you know. With the LED's the load is less so it also hyperflashes. I have no idea why the old one works - luck of component tolerances maybe? I too would recommend a bypass. The resistors are a crappy solution to the problem. You have to cut-up the wiring or use the wire taps that aren't sealed which can just cause more problems down the road.
