Do you have any other ultrasonic remote transmitters? Most of the time at least one of the frequencies will do something on another set.
When there is no load on a resistor (no current being drawn through it, one end disconnected) there should be the same voltage on both sides. There is only a voltage drop when current is being drawn so if you have 175 volts being dropped to 88 through a 1 meg resistor:
using E=IR (voltage drop=current times resistance)
87 volts being dropped= I times 1,000,000
divide 87/1,000,000 equals .087 milliamps (if my math is all correct)
this leakage could be caused by a carbon path on a terminal strip or some other very slight cause.
Also, what kind of a meter are you using...electronic (VTVM or digital) or an analog VOM? Some types of analog meters draw some current and the meter may be drawing enough to cause the voltage drop on the resistor.
