Review on 🔧 Tool Aid SG 23500 Back Probe Kit: Premium Blue Tool for Efficient Electrical Diagnostics by Jeff Wells

3 month daily usage test. I use them daily for automotive electrical diagnostics. good condition. These probes are great for reverse connector testing, penetration testing, and are small enough not to push terminals apart when testing sockets. In 3 months of daily use 2 wires broke out of 5. It's real agony when you're trying to troubleshoot a continuity problem only to find that 4 hours before repairing one of the test wires has died. Tip: Test a known good source before testing the power supply. Before checking for continuity, check the wires against each other. Always and now and then during longer diagnostic hunts. Much luck.
