Katzco Voltage Continuity & Current Tester - 6-12 V DC / 24 V AC Circuit - Heavy Duty -Long Probe Tester W/Indicator Light - 54 Inch Cord For Low Voltage Systems, Cars, Live Wires, Fuses -

Good quality from a reputable company 😀

Used to check continuity on circuits on my vehicle. Would buy again.

Impressed by the length, gauge and material of the cord and overall ruggedness of it. You can use this to check your ignition module by seeing how far the spark will jump from the plug wire, you can check both by distance and light brightness and you cant do that with an led type. These are best device for checking fuses in no time, hook the clip to gnd and on each fuse you will see a little tiny solder bump above each pin, just touch it with the ultra sharp point and watch the light. If your looking fo a blown fuse this is fastest way, go right down the line. I check 20 fuses in under 1 min. I've dropped this and banged it several times it wont break. Theres valid complaints on the crimping and soldering but com'on this id delivered to your door for 10$, how hard is it to fix a crimp or add some solder? Be careful the metal tip is a home defense weapon, this is hard hard metal and its razor sharp, it will easily cut deep into a finger or go straight thru you on a slip and fall. I have a large knife and gun collection but I ground down the tip for safety reason, Im sure you can put it right thru the hood or door/fenders on your car. Use it aw well to gnd othe light bulbs or coils, this can work just like a switch all the time and led types have problems doing that.

Great little tester that I didn’t know I needed in my tool bag

It is really bad quality. bulb is really not bright and assembly is also $10 product. never recommend it.

Works
