Speedometer and odometer aren't moving. Had my speedometer fixed by a professional. Installed speedometer back in dodge, it no work. Distance sensor swapped out. Still no work. What do I need to check in my dodge before I say issue lies with the "fixed" speedometer?

P.S. In factory service manual it says to test for continuity between two points but only shows one of the two points. Any idea what the other is?

What is a distance sensor test?

is the voltage gauges working? when driving you would test for resistance between the distance sensor input pin and ground. the faster you go i think the lower the resistance should be because the shorter pulse will be.
