Quoted from jsa:I wonder if my solder lugs are working the way I think they should... Sounds like something to validate in the morning.
I use lugs too. I have from time to time run into a situation where when screwing in a screw, the wood mushrooms up from the threading of the screw separating the contact of the lug from the lamp base. When you’re testing the continuity of the common braid are you putting one probe on the end of the braid and then touching each lamp holder in the string with the other lead? Not the screw tab or solder lug but actually further up on the arm of the lamp holder. It should buzz on each lamp. With a bulb in I also test by one lead on the end of the common braid and another on each tab on the top of each lamp. It should buzz this way too since the bulb is completing the circuit.
