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

These are good styli if you want to inspect a PCM connector or any connector with small pins without the risk of the pins open too much far away. I use them a lot and they are good, but the alligator clips can sometimes be a problem with leashes. I wish there was an adapter for threaded wires. Overall they're great for testing, just make sure those alligator clips make good contact.

Key points 1 and 2: The adapter wires [loosely] on the banana spring on the stem of the plug, they had to be soldered. So if you try to rely on them to get accurate ohm readings, you're only going to get worse. Solder them or throw them away. The return probe body OD is too large, it will not [fit] your standard Fluke leads; However, if you trim this case about 1/4 inch, they can be used. Hope that helps.

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…

This reverse probe set came in very handy when measuring voltage and resistance in vehicle wires. Be careful when handling as the tips are VERY sharp and can easily penetrate skin. Each sensor is supplied with a clear rubber cap to protect the tip and the person using it. However, the cap can easily be lost. This kit helped me troubleshoot a problem between the in-vehicle unit fuse box and the engine control unit (ECU). The needle is thin enough to fit between the connector housing and the pin,
