Just some info I was a TV tech. The turn signal switch provides a ground after power has gone thru flasher and lights. The hazard warning lights are hot all the time thru the switch on the column and turn signal switch gets power thru key switch when turned on. Two separate fuses #5 and #8 on chevette fuse block. If turn signal switch or wire to it were grounded lights would just be on. One terminal on the flasher itself goes to ground and one terminal gets two power wires. The third terminal goes to lights after going thru flasher circuitry to make it blink
