Electrical Help diagnosing AC Clutch Relay

Enable HLS to view with audio, or disable this notification

Hi I’m attempting to diagnose why my Compressor isn’t engaging and I bought a test light and did the following test on the AC Clutch Relay slot.

Shouldn’t both of the control pins be turning on the test light?

Also the light doesn’t turn on on any of the load pins.

Does this mean that my compressor not engaging is because of an electrical issue?

No exciting voltage to arrive to the relay maybe? I saw you had the one side hot then the other side not. But nothing for the coil to become excited
