Expert Reply:

I would start by using a hook probe tester like the # PTW2993 to check and see if you're getting a power feed on the wire coming out of the box on the Curt Spectrum # C51170 when the knob is plugged in. This will give you an idea if the knob might be faulty or not.

If you can let me know whether or not the box of the Spectrum is providing power out we can troubleshoot from there.
