•Quickly and safely tests high and low voltages on all vehicle voltages, including computerized engine.
•Checks hgih and low voltages (power and ground) on 6, 12 and 24 volt system.
•LED indicates red for power (high) and green for ground (low).
•High impedance to protect sensitive electronic sensors, microprocessors, electronic ignition components and air bags.
•Connects the red lead to a power source and the black lead to a ground source.
