Another electrical question

[Hotchef181818]

Were you measuring the 85v at the screw on the left switch where both the incoming hot and jumper to the right switch are ?
Or were you measuring the 85v at the screw with the wire going to the light ?

Red lead top, common lead bottom(hot and jumper), still learning how to use a meter so that could be wrong as well but I did the same on the other switch and showed 121 volts so I assumed I was doing it correctly.

Post up some pictures tomorrow of you taking these measurement, so we can rule out "operator" error, and figure your problem out. (Pun intended).
