The 12V Electronic Automotive Relay Tester is a specialized handheld diagnostic tool designed to provide a quick and accurate "Go/No-Go" health check for the most common automotive relays. By simulating real-world operating conditions, it allows technicians to identify faulty components without the need for complex multimeter testing or manual circuit jumping.

Elite Performance & Accurate Detection

• Instant Health Assessment: Automatically tests the coil and contact pins of 12V automotive relays to determine if they are functioning correctly.

• Cyclic Test Logic: The device cycles the relay multiple times during a single test to check for intermittent failures, contact "pitting," or excessive resistance.

• Dual Pin Support: Features a universal socket design compatible with both 4-pin and 5-pin electromagnetic relays.

• Alternator & Battery Analysis: Provides basic diagnostic feedback on the power source, ensuring the relay is receiving the correct voltage for operation.

Professional Hardware & Smart Diagnostics

• Tri-Color LED Feedback: Features a clear visual interface:

  • Green Light: Relay is functional and passed all cycle tests.

  • Red Light: Relay is defective (coil failure, welded contacts, or high resistance).

  • Yellow/Status Light: Indicates the tool is ready or checking for proper battery voltage.

• Portable & Battery-Powered: Connects directly to the vehicle's 12V battery via heavy-duty insulated alligator clips, making it ideal for roadside assistance or under-hood diagnostics.

• Safety First Design: Engineered with over-voltage and short-circuit protection to prevent damage to the vehicle's electrical system or the tester itself.

Technical Specifications

• Voltage Requirement: 12V DC (Vehicle Battery).

• Compatibility: Standard 4-pin and 5-pin automotive relays.

• Cable Length: Approximately 1 meter for flexible reach around the engine bay.

• Housing: Durable, anti-slip ABS plastic designed for rugged workshop use.
