Just because you hear a click from a relay doesn't mean its working. The click is the electromagnet pulling in the contact for the load circuit. Over time that contact gets charred and burnt and will no longer pass current. This is more common in a bad relay than to not hear the click. When testing relays you need to first put 12v to the trigger side and see if it does click. Then you need to leave it plugged in, trigger the relay and check the output voltage on the relay. If you do this unplugged you may read 12v no load but that burnt contact will pass voltage but not current. Thus it will read 12v free but under load it may read.03v for example.
You should always test relays in circuit.
You should also confirm you have 12v on the feed circuit for the load circuit. If there is an issue before the relay it's obviously not going to work.
Also, all the switches in the system are tied together, so as I said before you need to put a gauge on it and check the charge level. Too much gas or not enough will kill the clutch circuit. You need to confirm the charge is correct. You could be doing all this testing over it needs gas or its over charged.
Let me know what you find.
