Description
Overview:
The Sealey TA131 Relay Tester is a compact handheld tool for checking 4‐ and 5‐pin electro‐mechanical relays commonly found in vehicle electrical systems. Built in a robust housing for regular workshop use, it performs quick pass/fail assessments to confirm whether a relay is operating correctly. By automatically cycling the relay and monitoring resistance and contact switching, it helps uncover intermittent faults that simple one‐off checks can miss. Clear LED indicators provide instant feedback, making it useful for both professional technicians and DIY users. Suitable for cars, vans, motorcycles and light plant with standard automotive relays, the TA131 is ideal for troubleshooting circuits such as fuel pumps, cooling fans, lighting, heaters, horns and wipers, helping you confirm the relay before replacing parts or chasing wiring faults.
Key Features:
- Tests standard 4‐pin (SPST) and 5‐pin (SPDT) electro‐mechanical automotive relays
- Automatic 10‐cycle test sequence to assess resistance and contact consistency
- Clear LED feedback: green indicates a functioning relay; red flags a failed cycle
- Helps identify intermittent faults that can be missed by single‐cycle checks
- Compact, easy‐to-handle form factor for bench or on‐vehicle testing
- Durable construction suitable for workshop environments
- Speeds up diagnostics by confirming relay health before replacing components
- Reduces reliance on multimeters for basic relay function checks
- Suitable for a wide range of vehicles using standard blade‐type relays
- Straightforward operation for both trade and home users
Typical Applications:
Quick diagnosis of relay‐controlled circuits on cars, vans, motorcycles and light plant. Useful for confirming relay condition in systems such as fuel delivery, cooling fans, lighting, heater blowers, horn and wiper motors. Ideal for workshop fault‐finding, pre‐fit testing of spare relays, and fleet maintenance where fast, repeatable relay checks reduce downtime.
