I've seen a few threads on this and am now experiencing the same issue. checked the pool Tuesday morning, saw no lights on my IC 20. Ok, blown fuse. I replaced the fuse yesterday (nothing at the local stores except for a complete kit...ouch) and this morning checked the salt cell, and lo and behold, blown fuse. Everything seems to be fine otherwise. I have a ground wire running out of the power center, everything is grounded. Anyone have any ideas on a multimeter setting which I should check or anything? My pb is mum on the issue - although we are currently having other issues with him. Any thing that I need to know Chemistry-wise?
Here's my chemistry as of yesterday
Temp : 84
I just cleaned the cartridge filter yesterday as well. Pressure is 21.
I think my details are in my sig, but I have a 13,500 gallon Viking Triton fiberglass pool. Pool was installed Dec 2013. All the equipment is Pentair, including their Whisperflo single speed pump.
I did notice that when I replaced the fuse the cell was reading high salt. I was surprised about that!
