Eliminating the need for ground wires or clips, this cordless circuit tester speeds up electrical diagnostics in automotive, marine, and RV battery systems. It operates across a 3 to 28 V DC range with a 1 Mohm minimum input impedance, drawing only 20 micro-amps to protect sensitive electronic control modules and sensors from damage. The 5.75" (14.6 cm) stainless steel tool provides visual, audible, and tactile feedback via an LED, buzzer, and vibration indicator when positive voltage is detected.
