ed,
Normally, when you have an automation system, the salt cell is connected to the load side of the pump/filter relay so that the cell never gets power when the pump is off.
I am not sure how your cell is wired... Things to check..
1. Is the green light on the Surge card inside your power center on?
a. If the green light is on it means the power center is getting voltage
b. Check to make sure the cell is plugged into the power center correctly
c. Measure the DC output of the surge card going to you cell. It should be 30 to 40 volts DC
d. If you have the right DC voltage, then the cell is bad.
2. If the surge card green light is off..
a. Check the Power Center fuse.
b. If the fuse is good, then test to ensure that there is voltage to the SWCG transformer.
3. How old is the cell?
Thanks,
Jim R.
