Curious if there are other methods besides using a circuit tester pen.
What would be your definitive method for testing if a relay is bad?

Apply 12 volts to the coil and listen/feel for the click. Swap with a known good unit.
Click doesn’t mean it’s good. The contacts can be faulty. So even if you hear it working I would still swap it to be sure
