Turn signal troubles

[Hester_prynne]

I just picked up a '76 cb750k. The turn signals do not flash, nor does the buzzer sound. The front left signal light turns off when I select the Right signal.The rear signal lights are off unless i select one side or the other.

Ive replaced the flasher with no success. Any other ideas?

I've included a video of the problem to help.
