    Start Relay Tester

    Is there such a thing? I have been taught to take it out and slap it against the palm of my hand to hear if the contacts are loose, but sometimes they are positioned so that removing and re-installing can be a pain. Is there an easier way?

    Could you apply 120VAC or 24 VAC, depending on the coil voltage, and measure continuity?

    I would like a tool with a 5-2-1 set of wires on one end and a set for line voltage on the other. hook em up hit a button and get a result. Green light good, red light bad.

    The problem is that line voltage will not be enough to open the contacts on a good potential relay. You would need to know that the drop out voltage of the relay in question is and you would need a step up xfmr to apply the drop out voltage.
