joe123 Posted January 8, 2017 Share Posted January 8, 2017 Hi I am just about to solder dropper to the track and would like to know how does a continuity buzzer work. What do I connect the crocodile clips to? is it the track that I am soldering and the solder wire. Thanks for your help. Quote Link to comment Share on other sites More sharing options...
0 Maitland Posted January 10, 2017 Share Posted January 10, 2017 One clip to the track, the other to the far end of the wire. How the buzzer works- the buzzer itself is a battery and a sounder. There's no sound because the circuit is open, at the croc clips. Close the circuit- touch the clips together- and the buzzer sounds. Open it again, and it goes off. Now you want to check if your solder joint is good, so connect one clip to the track- it's still open circuit, so no sound. Touch the other to the (bare) far end of the wire. If the joint is good (and the wire isn't broken) the circuit is closed and you get a noise. If you don't, the joint is bad, or the wire is bad, or the clip on the track has pinged off while you weren't looking. Quote Link to comment Share on other sites More sharing options...
0 joe123 Posted January 11, 2017 Author Share Posted January 11, 2017 Thanks Maitland for your help. That explains things. I thought that you connect the crops clips to the track and if you made a wrong connection the buzzer would sound. Thanks again. Quote Link to comment Share on other sites More sharing options...
