Funny 4 out of 4 Polaris ones I have used all have cutout issues.
All within a couple days of install.
(I did the added screw, delete washer business to make sure the plunger was depressed)
No change.
After that they always get disconnected.
See why they failed. Should never need to add a screw. Mine have all worked flawless with out adding a screw. I do delete the washer though.
