I called goldline and they said it is probably the main board.
Goldline aqualogic no cell power 2.
Plug both wire to the fuse directly.
Goldline controls warrantied these flow switches if they failed in the field and were of the specified lot.
Same with the serial numbers on your cells and control boxes after the 5a 5e 5l 3l and 3e.
If no voltage is measured continue to step 1b.
If you get no cell power before doing anything else here s the easiest testing method.
If the voltage is ok go to step 1c.
Verify that 20 24 volts ac is present between the two yellow wires.
G flow monitor flow switch connector h p transformer input 120vac x 2.
Please add liquid chlorine to the pool until the issue has been resolved.
Turn on the main braker and your goldline.
This must be resolved by a certified technician.
Please contact tech service.
I tried cycling the system at the breaker level on the panel thinking there might be a glitch as well as re seating the cell connector that plugs into the panel.

The first 2 digits are the year of manufacture the next two the month.
Try starting the filter pump.
My display is saying chlorinator off no cell power and check system no cell power 2.
No cell power cell power error low volts stop.
