Chris depends if its a circuit or an appliance thats at fault
An insulation resistance test would reveal any circuit that has a fault to earth, but that is done with everything unplugged / disconnected.
An insulation test on individual applainces MAY show up the problem, but either way, if you havent got an IR tester its irrelevent!!
