Mizzou, to see if the unit is producing, first remove the cell and visually inspect it. Then fill a bucket large enough to hold the unit with water and submerge the unit - only have the bucket full enough to cover the cell, don't soak the cord. Now 'trick the unit into thinking that the pump is running by holding the flow switch closed. You should see tiny hydrogen bubbles being produced in the bucket - as a second measure test the bucket water for chlorine - after ~ a minute of the cell running it should be off the charts on an OTO test

There is a chance that the SWCG is 'slaved' to the pump motor, if so you'll have to figure out a way to get the SWCG unit on without the pump dumping water out of the return line (which now has no cell on it to get the water back into the pool) - I can help, but would need some specifics on your set-up.
