Well.....there is the simple way....

 

-Listen for it to 'click' as its being commanded on. However, the contacts inside could be burnt, so it could sitll be faulty.

 

-With jumper wires, supply the relay with 12 volts on the controlling side and check to make sure that the controlled side has contiunity with a ohmmeter.
