Fred,
Thanks for your advice. No, I haven't gone as far as you suggest--I guess that should be the next step. Can you tell me where to find such a buzzer tester. In addition, can you briefly explain how you hook it up, for example, on a light fixture in order to test for the short? Do you place it between the bulb and the wire hookup, then check/wiggle wires to listen for the short? Thanks in advance for your further advice.
Jim
