It helps to have someone inside to run the key for you.
Key off- put your multimeter black probe on a good ground and the red probe on the large post of the GPR closest to the fender. Should have around +12V. Now put the red lead on the other large post, should be 0V.
Key on (but not cranking)- both large posts should have +12V. If there is more than 1V drop across the relay it's time for a new one.

Not sure what you mean, Phil, but when my GPR was going out, I could hear it "clicking" on and off with the engine running. Is that what you mean by "stuck on" or are you referring to something else?
