Lets just use a DMM. The test cord will cause a 120vac dead short.One other thing to try is to make sure the switch works and the contacts close. If you don't have a meter, you could use your test cord with a light bulb as a tester. You can remove the switch and apply a vacuum by "sucking" gently on a hose attached to it.
