Review on ALLOSUN Power Probe EM287: Electric Circuit Tester for Voltage, Polarity, Continuity, and Short Circuit Tracking with Overload Protection by Logan Collier

Aside from a great price compared to others. a simple test, as well as checking voltage, switching power, reading or listening to voltage. Make sure you read the instructions and don't mess with any serious 12 volt stuff. even you protected him. The cure for learning isn't much, but read the instructions a few times, practice testing simple things. Get to know the tool. The umbilicals are quite long and are enough to cover the entire area of the vehicle's engine compartment or to test trailer brakes and lighting systems with one battery. The rest is not bad. except my probe was missing! the round metal probe was mia it wasn't in the box so i had to make one out of wire the size of a stainless steel hanger and i sharpened the end too sharp put it in the tester added some epoxy and it worked.
