Electronic Specialties 190 Relay Tester 4 And 5 Pin Automatic Test Tool

The Electronic Specialties 190 relay tester provides a fast and reliable way to verify the performance of common 4 and 5 pin automotive relays. Designed for off vehicle use, this tester runs an automatic test cycle that repeatedly energizes the relay to confirm proper switching. It clearly identifies good or failed relays by monitoring performance during each cycle. Powered directly by a standard 12V vehicle battery, it removes the need for external power supplies. By loading the switch contacts, the tester helps detect excessive resistance that can lead to electrical problems, making it a practical diagnostic tool for automotive electrical troubleshooting.

• AUTOMATED RELAY TESTING: Performs automatic testing on common 4 and 5 pin relays by cycling each relay through multiple test sequences to confirm functional operation without manual steps
• GOOD BAD INDICATION: Clearly identifies relay condition with a simple pass or fail result when any test cycle is unsuccessful, helping quickly determine whether replacement is required
• OFF VEHICLE DIAGNOSTICS: Allows quick and convenient relay testing away from the vehicle, reducing troubleshooting time and eliminating guesswork during electrical diagnostics
• VEHICLE POWERED OPERATION: Operates using a standard 12V vehicle battery connection, eliminating the need for standalone power sources or internal batteries
• RESISTANCE DETECTION: Loads switch contacts during testing to help identify excessive resistance that may cause intermittent electrical issues in real world applications
