Review on Heavy Duty 3-48V Digital LCD Circuit Tester with Extended 140 Inch Spring Wire for Cars and Trucks - Low Voltage & Light Tester with Stainless Probe by David Batte

I know "modern techies" will laugh at test lamps as barbaric or archaic system troubleshooters, but in the end they are a quick method to use can be used to reduce diagnosis time and headaches. This is a good piece of equipment (especially for the price) and a welcome addition to my field box. Does it replace the force probe? Of course not. But in the same way they are completely different tools, not even at the same price as for use as a basic tester. similar to pluggable and higher terminals). Sometimes it can help to troubleshoot heavy equipment (AC systems come to mind) by clamping it to the positive terminal and seeing if the ECU is giving a ground signal. Not a huge flaw, but one thing that's good about basic lamp test lights.
