Test Alligator Clips for Continuity

 
Always test your tools for continuity before placing them in your tool box. A faulty tool will lead to time wasted with your prototyping.
 
To test your tools – Set your multimeter to the audible continuity setting and touch both ends of your alligator clips and jumper wires.
