Review on 12V Automotive Relay Tester - Electronic Car Battery Diagnostic Checker, Scan Tools with Clips, Battery Buddy Code Reader and Voltage Tester Screwdriver by Jimmy Jefferson

Revainrating 5 out of 5

Ease of use takes the guesswork out of it

This is a compact and easy to use application. This takes the guesswork out of relay testing. The relay may work but has a bad contact causing a voltage drop. This tester will make it easier to decide if the relay needs to be replaced.

Pros
  • Voltage Detector Pen: With 3mm slotted head, the working voltage is 100-1000VAC. The circuit tester pen's neon lamp emits light when the pen detects AC voltage. To test the circuit and determine if the object is electrified.
