Portable Automotive Relay Tester (Battery Powered)
Fast, Safe, and Reliable 4-Pin/5-Pin Relay Diagnostics
Product Overview
This professional-grade diagnostic tool is designed for quick and accurate testing of automotive relays. Powered via Battery, it evaluates coil continuity and contact status for both 4-pin and 5-pin 12V relays, delivering precise results in under 10 seconds. Its compact design and built-in LED lighting make it an essential tool for automotive technicians and DIY enthusiasts alike.
Key Features
- Dual Compatibility: Supports most 12V electromagnetic 4-pin and 5-pin relays.
- Rapid Testing: Instant detection with a full diagnostic cycle completed in 10 seconds.
- Power Options: Battery
- Built-in LED Work Light: Integrated side lighting for easy operation in dark engine bays or under-dash areas.
- Smart Alerts: Dual-color LED indicator and acoustic "beep" prompts for clear result interpretation.
Operation Guide
- Power On: Press the circular "ON/OFF" button.
- Select Mode: Toggle the switch to either "4-Pin" or "5-Pin" based on the relay type.
- Initiate Test: Insert the relay and press the "TEST" button to start the 10-second diagnostic.
- LED Lighting: Use the side switch to toggle the built-in LED for dark environments.
Understanding Results
- NORMAL (Pass): The Green Light flashes once per second (10 times total) accompanied by a rhythmic "Beep-Beep" sound.
- FAULT (Fail): The Red Light stays on immediately, indicating a relay malfunction or internal short.
Important Notes
- Re-testing: To perform a new test, simply press the "TEST" button again after a cycle finishes.
