12 24v Relay Tester, Car Relays Circuit System Diagnostic Repair, 4 Pin/5Pin Detection Tool For 10 In 5 Different Foot Positions

Automatic 12V/24V Relay Identification: The OBDResource relay tester can test 12V/24V relays at 5 different pin positions, automatically identifying types and displaying the overall status and functions of common automotive relays. Simply connect the automotive relay to begin testing. One-button operation enables quick fault detection. It supports manual switching for testing 4-pin or 5-pin automotive relays. Wireless and Portable Design: Car relay tester does not rely on vehicle battery power, allowing relay fault detection anytime, anywhere. It operates on just 3 AA batteries (not included) or can be powered via the included Type-C cable connected to a power adapter, computer, or power bank. Extensive Compatibility: Not only does it support 12V/24V relays, but circuit system diagnostic repair is also compatible with 5 pin-type variations of 4-pin/5-pin relays and over 20 relay models. There’s no need to worry about compatibility with the relays you need to test. Thanks to its broad compatibility, it serves as an ideal diagnostic tool for automotive relay troubleshooting, whether for home use or professional workshop applications. Safe and Rapid Testing: This is a safe and non-destructive automotive relay testing device. Whether the automotive relay is normally open (NO) or normally closed (NC), the OBDResource relay tester vehicles can accurately test it. When powered by batteries, it automatically shuts off after one minute of inactivity, eliminating concerns about forgetting to turn it off. Audio and Visual Alerts: Equipped with dual-color red and green LED indicators and a buzzer. During testing, audio and visual prompts are synchronized—the buzzer sounds when the test begins, and upon completion, a red light indicates a faulty relay, while a green light shows battery status and whether the battery level is sufficient.
