Got one that happens intermittently. It has done it a couple of times while we are there and then start back to working when performing checks. It will go on low oil, and the complaint is and has been witnessed by us ..pump comes on but does not go up. The few times we did get to trouble shoot by checking voltage at UFS1 and UFS2 we dont have any and then as if by magic we get it and it starts working until the next day. Checked switch tree and switches, wiring, had a spare relay board and put that on, but still persist.

Welcome any suggestions.
