Pentair Superflo VS 342001 pump causing frequency problem with salt generator

My Pentair Superflo had a short in the feed that damaged the main board in my Jandy salt cell. Rewired pump and replaced board and everything works fine except whenever the pump is running the salt cell is not getting 60 Mhz and will not generate.
 
I’m not familiar with any 60MHz signal associated with pool equipment. What are you measuring and how are you measuring it?

When the pump runs, does the flow switch for the cell close?
 
The salt generator is showing an error code for not getting the 60MHz that it requires. That error code prevents the flow switch from closing. When I jump the salt generator from a power source isolated from the pump, the flow switch closes and the generator works fine.
 
What model SWG are we discussing and what error code are you getting?
 
How is your pump and SWG wired to your power?

Show us pics of your wiring.

The pump and salt cell are both wired together along with a booster pump for pool cleaner thru a time clock. I've confirmed the issue still exists with the booster pump disconnected. I also confirmed that the salt generator works fine when feed from a separate power source. I definitely think the variable speed pump is causing frequency variations that the salt cell cannot handle. I'm just not sure what caused the issue to present only after the pump had the short.
 
The Hz is 25 with the pump running, 60 when it is not. The voltage is 118.
If the supply to the cell is 25 Hz with the pump running, is it possible you have the cell wired to the pump motor after the variable frequency drive? As an experiment, increase motor speed until you read 60Hz or so at the cell. Does it work properly when you do that?
 
There is certainly frequency noise from the pump that was not there before. The question seems to be do I replace the drive or the entire pump?

The SWG is only supposed to be powered when the pump is running so I do not want to power separately. Plus it is nowhere near an alternate power source.

Explain exactly what happened here and what you did to repair it.

It sounds like the short damaged some of the electronics in your pump drive. Did your replace any parts in the pump?
 
Maybe a defect in the drive caused by the short.

The drive might work for years and it might fail today, hard to say.

Maybe there is still some sort of defect in the wiring.

The drive is usually pretty expensive, so you need to see the price difference and consider the age of the pump.

I would power from a different power supply and use a timer to control the on and off to be in the pump run window or just run the pump 24/7 at low speed.
