You may recall? Might have been last winter or the one before, my heated screen stopped working, both sides at the same time, just instant really, all the signs, to me anyway, as an electrical failure, ie- fuse or relay sort of issue. It was later in the year when it was dry and warm that I investigated further as it involves stripping off all the stuff I've just stripped off today, to access the two screen connections and the earth stud. I had power testing there, both sides but forgot to do a continuany test for the elements themselves, only remembering after I had reassembled stuff. Had to remake the earth stud as that snapped off.
I then thought maybe I had a dodgy cable with broken strands or something so I purchased a dc clamp meter which I can't remember what the results of that test were but they were nothing like I should have seen and I think the clamp was faulty and gave up after that. It's hard to motivate yourself to diagnose a heated screen when the sun is burning your skin off
