i used the wall voltage instead of dc an put a 100k resistor in there. i
measured a 13v drop across the resistor when i hooked it up to one pin but when
i hooked it up to another i got a 32v drop. my resistance meter said that those
two pins were not connected. im assuming that for the 13v drop there is just
one(or a few) more diode between the pin and the hv line. is that it? which one
should i use for my ground?
