SG Tool Aid 23500 Back Probe Kit

Comparable to more expensive options. Have been using almost daily over a year and holding up so far.

Great addition to any tool box to step up your electrical testing abilities. I was just using paper clips but these work 100x better. I use these at least twice a week for the last 3 months. I work on very finicky heavy equipment electronics so a set like is a must.

Works great for backprobing connections.

This back probe kit was very handy when measuring voltage and resistance in automotive wires. Be careful when handling because the points are VERY sharp and can easily puncture skin. Each probe comes with a clear rubber cap to protect the tip and the person handling it. However, the cap could be easily lost. This kit helped me troubleshoot a problem between an automotive fuse box and engine control unit (ECU). The needle is thin enough to fit between a connector's backshell and pin yet still make electrical contact.The durability of the probes are good but I noted 1 needle fell out from its socket. It can be reinstalled but there is nothing to lock the needle into place. As long as the needle is supported during removal and installation then it shouldn't be a problem. This is a delicate item so will not take much to break it.NOTE: These probes are not meant to pierce the protective sheath of the wire. It is intended to make contact with a metal pin or socket inside a connector without causing damage to that connector.

This tool is sold by MATCO for twice as much. It is the exact same tool number with a different lable. So to get it at half price and not have to wait on a tool guy to get it is well worth it. The kit does everything its designed to do no mater what you are working on.

The work well in most cases I can probe the wires through the back side of plugs.

Easy to use. Probes are set at different angles to get into tight spots. I have been working on lift trucks sense 1976 and these do what I need them to do

Awesome little kit for backprobing. I especially like the fact that there are also 45 and 90 degree for the hard to reach areas. The banana/alligator leads are icing on the cake. I used to only use sewing T pins which worked fine but have to be careful when probing close to each other because of the potential to short them when testing. This backprobe kit doesn’t fully eliminate shorting accidents but greatly reduces them with the plastic end of the probes. Another great feature I personally like is the probes are different colors so at a glance you can differentiate different circuits and also keep scope leads color coordinated with the channel leads. Lastly the case for the probes is compact and lightweight so it’s not cumbersome to store or bring with you
