Review on 🔌 Katzco Voltage Continuity and Current Tester - 6-12 V DC - 24 V AC Circuit - Heavy Duty - Long Probe Tester With Indicator Light - 54 Inch Cord for Low Voltage Systems, Automotive, Live Wires, Fuses by Dan Tsourvakas

Impressive cable length, gauge, material and overall strength. You can use it to test your ignition module by seeing how far the spark jumps from the spark plug wire, you can test both the distance and the brightness of the light and you can't do that with the LED type. This is the best device for a quick fuse test, connect the clip to ground and on each fuse you will see a small tiny solder joint above each pin, just touch it with the very sharp end and watch the light. If you are looking for a blown fuse this is the quickest way, go straight. I check 20 backups in less than 1 minute. I dropped it and hit it a few times, it won't break. There are legitimate complaints about the crimping and soldering, but this ID comes to your door for $10, how hard is it to fix the crimp or add some solder? Be careful, the metal tip is a home defense weapon, it's hard carbide and razor sharp, it easily cuts deep into your finger or goes right through you when slipping and falling. I have a large collection of knives and pistols, but I have sharpened the tip for safety, I'm sure you can stab them straight through your car's hood or door/fender. Use it well to ground other bulbs or coils, this can work like a switch all the time and LED types have trouble with it.
