Smoothed boot? Best way to test would simply be apply 12v directly to the popper. If it "pops", it's working, and the problem is wiring, if not.....well, you work it out. 
EDIT: assuming it's actually a 12v popper, might only want 5v maybe? Guess there should be some kind of markings on the popper (assuming you can see it easily) to confirm?
