The power probe can indicate voltage polarity, check switches, relays, the on/off activation of diodes, fuses, and circuits, as well as monitor and detect short circuits.

It features a long cable, which allows any electrical system to be tested with ease. It is highly sensitive and has short-circuit protection, while it can immediately check for poor ground connections.

Its use is easy, without complicated procedures, convenient and practical.

It can test the polarity of electrical wires and plugs, suitable for truck and car manufacturing.
