Aquatrol assistance

I have Aquatrol r1.47 RJ. It has been working for years with a T5, which finally died. I got a Hayward T15 and jumpered J4. It thinks the salt is 900 (its really 3000). My numbers are 93, 27.4, 3.22, 100p, -900,AL-7,r1.47. The plumbing is the same as has worked for years with the old T5.
Average salt is 900 on display. I turn off and then On, wait 5 seconds and it generates a ton of chlorine (I can see the bubbles in a clear section of tubing. Then after another time, perhaps 20 seconds, it shuts off chlorine generation and lights up "inspect cell" and "check salt".
I wonder. It almost appears as if the J4 jumper didn't take properly. What do you all think? Should I take it apart and double check the jumper?
 
Yup, it is behaving like it expects a T-5 cell.
 
The amps are way too low.

Either the cell is bad or the salinity is much lower than you think.

Can you show the cell serial number and label?

Test the salinity two different reliable ways.
 
Voltage stays steady. Amps stay steady, but only until it decides there is not enough salt. Salinity has been checked by pool company and our very reliable separate tester. I put the jumper on and put it to T5 setting and it thinks salt is 1900. Put it to T15 setting (its actually a T15) and it thinks salt is 900. Those are the only 2 settings I can set. So the J4 jumper is doing something. I did check my soldering of the J4 with a meter and its good. I soldered pins and put a jumper on it so I can switch back and forth. So resistance is too high. The unit was NIB with Hayward label on box and on cell.
