I live in Florida and we recently had a lot of rain. My display read 2600 (I usually keep it at 3000) and my inspect cell warning also came on. I added a couple bags of salt and now it's reading 7100!! - would a dirty cell cause this? I haven't cleaned it yet but all I've read here is low readings on bad cells, not high. I tried removing the cell last night but it was so tight I couldn't get it off without some kind of tool which I don't have. I'll try again today; any advice is appreciated. Thanks, T
