You already have the maximum available quantity in your cart.
The universal CNBJ-707 relay tester is a simple diagnostic tool for quickly checking automotive relays. It operates on a go/no-go principle and verifies the correct function of relay contacts by connecting to the car battery. It is suitable for 4 pin and 5 pin relays, which can be switched using a sliding switch. The tester automatically checks the pin configuration, the activation and deactivation time, and the consistency of the relay during the test. Upon pressing the TEST button, it assesses the relay's status and displays the result using a coloured LED. The green LED indicates a relay in good condition, while the red LED warns of a faulty relay. It draws power directly from the car battery using crocodile clips, eliminating the need for a separate power source. The 90 cm long wires with crocodile clips allow for convenient connection even to more distant terminals.
Main features:
- Relay Testing — 4 pin and 5 pin relays selectable via the 4PIN and 5PIN sliding switch
- LED Indication — green LED indicates a relay in good condition, red LED indicates a faulty relay

The CNBJ-707 relay tester simplifies the quick identification of faulty relays without complicated measurements.
