The perfect electrical circuit test assistant! Get the job done with ease!

Compatible with standard 4 and 5 terminal relay circuits and can be used with most car makes and models. The RelaySim Pro can energise any relay that powers DC electric motors, fuel pumps, cooling fans, blower motors, window motors, and any other motor actuated by a relay), headlights, and other car lighting applications or almost all electrical actuators, such as electromagnetic, electromechanical, and electrohydraulic. Additionally, it can be used in series (in place of a fuse) with most other circuits rated for 25A or less. The device is suitable for both 12-volt and 24-volt systems and does not limit the operating current range. The operating range for continuous usage is up to 21 amps. The device supports a maximum surge of 27 amps, regardless of whether the voltage is 12V or 24V. Two LEDs (85 and 86 terminals) indicate voltage, polarity, and continuity in the relay coil circuit.

RelaySim Pro has a built-in dual high-definition LCD digital display that allows you to observe the current and voltage values in the circuit under test. The device measures the current flowing through the 87 or 87a circuit, depending on which one is currently activated. Also, it measures and displays voltage for circuits 85, 86, 87, 87a, and 30. You can directly observe the amperage and voltage going into an activated circuit, allowing you to assess the load's health. If an actuator is drawing more current than specified, or the current load is inconsistent during operation, the load/actuator is suspect and should be replaced.

This circuit tester is suitable for use with standard 12V DC systems, as well as newer 42V systems. Safe for low current circuits as it only draws 3 milliamps @ 12V. Crystal clear handle providers excellent all round visibility, even in bright light.

• Automotic voltage identification: 12V (blue LED) | 42V (red LED)
• Two super bright LEDs for excellent visibility in all light conditions.
• Safe for low current circuits
