What type of ohmmeter are you using and on which range?
That's what I did. I pulled it apart and checked all the resistors at the solder points and then because of my disbelief, I checked them all at the legs of the resistors.

I have a Fluke 87, that works perfectly on auto ranging. I have the tone on and can't get a beep or anything. The Fluke, I use daily, so no question there.
