Head to your local parts store and get you a heavy duty flasher and your problems should be over.

You should have two flashers, one for the emergency blinkers and one for the directional signal blinkers. At least, I have two in my '78. The flasher on the fuse panel is for the emergency blinkers. The directional flasher is mounted under the dashboard, to the left of the steering column.
