I just replaced my SWG and put on a new flow sensor with the jumper. Yes it is the one with the black epoxy. I'm getting no error codes, but the SWG constantly switches between Cell On and Cell Off. I mean every few seconds. Could this be a control board problem. I have recalibrated, I have made sure everything is the correct current, etc. I don't see any obvious burns on the board. I have read every thread on this and cannot find my answer. Any help would be much appreciated.
