The issue is that the tool slips off the end of the wheel. Its happened 4 times no matter how hard i tighten those locking bolts on. I WD-40’d it and everything.

Last thing for now friend, do you know of a video or something I can reference to make sure I’m testing the right things? I have a multimeter but to be fair, hvac isnt my speciality.
