An essential diagnostic tool for testing potentially faulty electro mechanical relays. This tool tests both 12V / 24V relays, with four / five pins (not late model Ford 4 pin).

Simply plug the relay into the tester - using 12V vehicle power, the relay will be cycled 10 times with the tester applying a signal to the relay coil while checking the function of the internal contacts. The tester applies load to the internal contacts to detect excessive resistance.

• Quickly test 3 common types of electro mechanical relays
• Test relay coil resistance / relay contacts / cyclic testing
• Relay coil resistance: 20 - 500 Ohms
• Test voltage for coil: 9V
• Contact resistance threshold: 200 milliohms

The Power Probe 4 Master Combo Kit combines the Power Probe 4, ECT3000 and various accessories to provide the ultimate combination of diagnostic and circuit-testing capabilities.

The Power Probe 4 provides simplified testing of Motors, Lights, Relays, and Sensors, and even Fuel Injectors. Also, like all Power Probe circuit-testers, it supplies Power and Ground for functional component testing on or off the vehicle. The ECT3000 will help you trace short and open circuits quickly and accurately.

An incredibly handy set of wheel nut sockets. These flip sockets include new half size sockets for chrome covered nuts which have become swollen / warped.

Inflated / warped chrome plated caps are a common problem, especially on some Ford vehicles. Standard sized wheel nut sockets will not fit, and a half sized variant is required.

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.

• Suits 12V and 24V applications
• Separate control of the 87 and 87a relay circuit
• Integrated a dual high-definition LCD digital display
• Built-in DC ampere meter 0...50A
• Up to 21 amp operating current (for both 12V and 24V applications. See the specs for more details)
