Low amp light flashing

AutoPilot Salt generator red light is flashing - says low Amps. Currently 12v, 3.1amp. I’ve replaced the cell, the power cord, and the fuses- and it still flashes. Don’t know the next step. Help please!

Which model AutoPilot is it? Do you have a model number of the control panel?

Model DIG-220

currently 13V, 3.6amp

thanks!
