The Innova 5420 Power Check powered circuit tester lets users quickly and safely check power and ground voltage readings on vehicles, including computerized controlled engines, electrical circuits, wiring, fuses, batteries, sensors, switches and motors. It also lets users safely test and apply power/ground to switches, relays, fans, and electrical circuits to see if they power on to troubleshoot a range of automotive issues. Power output options include 3V, 5V, and 12/24V applications. Its digital screen and two-color LEDs display the system voltage (red = low / green = good) reading and power/ground for quick readings of electrical circuits. Innova’s Power Check also features a proprietary swivel-head, which enables the user to access difficult-to-reach areas. Its 10 MegOhm impedance provides enhanced safety for automotive electrical system testing such as inputs to a car or truck’s PCM.
