i have a ps-8 with a t cell 15.... i'm pretty sure it's bad as it's been reding <2000 and my dropper kit says almost 4k... it does however seem to always start out at 3000-3200 when i just turn on the pump after its been down for a little while. i can do the save instant slat level at that time, but it always drops back down to 1800 or so and shuts down the cell. does this sound at all familiar?
thanks all
