How to backprobe an electrical connector and test an electrical circuit
When you’re checking live voltage readings on sensors, the challenge is How to backprobe an electrical connector. Some pros stick a pin through the wire. But these piercing claws from Ferret make the job much easier.
Isolate the wire carrying the signal you want to monitor. Then position the wire in the cradle of the “claw.” Screw the piercing probe into the wire and then attach the lead from your digital multi-meter into the end of the Ferret Claw. It gives perfect readings every time. When you finish the job, apply a dab of finger nail polish to seal the puncture hole. Do NOT use RTV. It causes corrosion on copper wires.
