Quick background. About a month ago my Easy Touch salt reading went to 0 PPM. When I checked the cell the red salt light was on and the cell would not cycle. Cleaning it did nothing. In short it was dead. I installed a new IC40 about two weeks ago. The salt readings came back and everything was working as it should. Well last night I noticed the salt readings were once again showing 0 PPM, however the cell is working properly, green salt light, and the cell cycles as it should. However I cannot control the cell with the Easy Touch. I can't change the percentage settings or put the cell in super chlorinate mode. Completely de-powering(tipped the C/B's) to reset it didn't work. So I opened the Easy Touch panel and found what looks like a burned pin on the 4 wire connector to the IC40. I'm guessing it's the ground wire because black? Never heard of burning a ground wire before. Anyway, this is what I found. I'm guessing it happened AFTER installing the new IC40?? Because as I said the readings came back, for a while, after installing the new IC40. Yes, the Easy Touch was powered down when I connected it. Guess I'll have to change both the connector and the board. Any thoughts as to why this happened would be greatly appreciated.
