OBDResource relay tester supports 4 different pin configurations (4-pin/5-pin), displays relay status(opening/closing) and function in real time, enables fast fault localization and does not require manual configuration.</span></p></li><li><p><strong><span style="font-size:16px">Wireless, portable design:</span></strong><span style="font-size:16px"> Auto relay tester is simply powered by the battery terminals and requires no external power source. This makes it ideal for outdoor or workshop mobile testing and overcomes the limitations of conventional stationary testing equipment. and the product weighs only 125 grams andjavascript; can be carried with you.</span></p></li><li><p><strong><span style="font-size:16px">Wide Compatibility:</span></strong><span style="font-size:16px"> Automatic voltage detection covers over 20 common automotive relay types, is with 12V/24V voltage and various pin arrangements (4-pin/5-pin) compatible and suitable for both private and professional repairs – without problems due to incompatible devices or relays.</span></p></li><li><p><strong><span style="font-size:16px">Safety and gentle testing:</span></strong><span style="font-size:16px"> Thanks to non-invasive testing technology, the internal relay circuit is not damaged. The device accurately detects the status of opening/closing relays and ensures a safe and reliable test process.</span></p></li><li><p><strong><span style="font-size:16px">Warnings for use:</span></strong><span style="font-size:16px"> OBDResource relay relay detection clearly indicates that the battery voltage (12V or 24V) must be suitable for testing, to avoid errors due to incorrect voltage. It supports only 4 pin configurations and reminds users of the correct handling to ensure accuracy.</span></p></li><li><p><strong><span style="font-size:16px">Use process:</span></strong><span style="font-size:16px"> The red battery clip must be attached to the plus pole of the battery and the black battery clip to the minus pole of the battery. at this point, the LED light indicates red. Insert the relay into the corresponding connectors, select the corresponding pin and press &quot;Test&quot; to perform the test. (If the voltage of the tested battery is lower than the voltage of the relay, the LED will remain red. In this case, a higher voltage should be used for the test.)</span></p></li></ul><p></p>
