Turn signals and bright lights

[slowboy]

I have a 1972 GMC P/U C1500. All of a sudden my turn signals stopped blinking and bright lights (high beam) stopped working. When I turn signal lights on they light up, but just don't blink. My low beams work.
I'm putting these 2 together because I want to know if they are connected some how. If not, I tested flasher and when I put meter to it I get a signal sound. This is out of fuse box.
My high beam switch on floor does switch from high to low when I press pedal.
Please let me know what to check on both of these problems.
Thank you
