Just did this exact repair today 5/29/17!! Worked like a charm. Thank you so much!I agree with Joe. This an old post, but what a great one. I had the same thing happen to me today. Fixed it in 5 minutes. Saved me at least $800
I went straight home and checked the solder point that was pictured and described on this forum and sure enough, mine was burnt out. I was able to re-solder the burnt point and started the system back up. The delay counted down and bam, it worked perfectly! I couldn't have done this without all of you helping & posting here. This has saved me hundreds of dollars on repair cost! I have attached a picture of what my board looked like before I soldered it back.Welcome to the forum.
Usually the solder joint causes the opposite problem. Low current, low salt or power is off to the cell.
The high salt warning comes on when the current exceeds 8 amps. This can be caused by high salt but also by high water temperatures. Do you have solar or a heater that when turned on causes this problem?
