Making a shrewd guess i would say the installer brought
the wires from the GFCI into the backbox of the light switch to
connect to other outlets and take advantage of the holes made
for the light cables and these wires were never connected to
the light.
So you have to separate the unprotected circuit from the
protected circuit once this has been done the GFCI will reset
and the lights will go back to being a simple straightforward
job

Can you tell how this bathroom light-switch circuit is wired based on
these
15 highly annotated photos?

The wierd thing is that the CGFI circuits (apparently downstream of the
light switch) stopped working altogether. There is no current in the GCFI
boxes and in adjacent outlets.

Another wierd thing is the voltage CHANGES when the adjacent bathroom
light
switch is turned on or off (but it does not change if I remove the bulbs
from the adjacent light switch).

Can you help me figure out the proper way a light switch should be wired
to
this box?
