6. Using a multimeter set for 200 ohms, place the red (+) probe on the terminal at the end of the black wire
(1). Test for continuity on each of the flat blades and then on the round pin of the AC plug. The tester
should indicate continuity on one flat blade only. If any other reading is obtained, the AC cord and plug
must be replaced.
