Was getting high salt/amps error yesterday with the numbers jumping all over before when in diagnostic mode before shutting down. I was getting a no cell power 1 error. I have soldered the k1 relay many times in the past. I was going through the Hayward trouble shooting worksheet and getting the proper voltage between yellow to yellow, orange to orange, 20a fuse test fine, but when I tested the red and black I am getting 55 volts instead of the 18-33v. The flowsheets states if the voltage is low or absent replace the rectifiers, however if the voltage is good, replace the main board. My readings do not fall in either category. Ironically, my board is running this morning with no error but is still testing @ 55v between red and black. K1, rectifiers, power supply? Any thoughts? Thanks.
