thanks
what would happen if i allowed it to do the leakage test? does this test not just put some current down the line conductor and monitor for leakage to earth ( this is with out the mains lead in so the pc will not start)
What you describe above is essentially a test of the power cord - which is the same as an extension lead. (I know you also need "polarity") If you pull the plug on the PC then your not testing this item.
