I'm chasing a problem with my SWG that started a couple weeks ago. Added salt one evening, the next morning got the no power warning on the SWG . Checked the 20Amp fuse, it was blown. Figured some new salt must have got in the cel and overloaded the circuits. Replaced the fuse, everything was fine. For a few days. Then I noticed the water temp was reading about 10 degrees high,and the salt was reading lower than actual (Taylor salt test). Did the research, figured the cel/thermistor is going bad (the T-15 is less than 3 years old btw).So I did the clean the cel and check for any debris but it looked fine. Then magically everything was back to normal. Temps were fine, salt was within 200 of actual, great. Then yesterday I check LOW SALT, Temp 115 ! (Water is really 85). Must be the cel so I Check the resistance across the correct pins on the cable. 7.68kΩ. According to the chart that's pretty close to the actual temp. Unless I'm reading it incorrectly. So what's wrong ? The Voltage and Amps seem to be close to spec. But my Salt is now reading about 1000ppm low. As tested it's 3200. My chemistry is a little bit old 12/24 exp. but it's been fairly accurate (I think). Fearing it may be the board I changed the Cel type to T-9. It now reads the salt accurately but the Temp is still way off. What am I missing ? these are the readings I got this morning.
Can the thermistor be bad but still read Ω close to normal? or is it something else?
