You would need to test for 240V across both leads, red and black. Otherwise testing one to ground you will get 120V on both due to current feeding through but zero volts when testing across both leads. So to be clear, you get the red heat indicator light to come on only when you jump the pressure switch? If so it sounds like that switch may be bad and needs to be replaced. Never leave it jumped after testing.
