The Old Way
- Fumbling with multimeter probes
- Swapping relays blindly to test
- Missing intermittent 'sticky' faults
- No way to check battery health live
With LamiWexi
- Automated 10-cycle pass/fail test
- Universal 4-pin and 5-pin support
- Digital LED live voltage display
- Precision diagnostic microchip
Everything you need to diagnosein one compact unit
Advanced 10-Cycle Verification
Our main control chip cycles the relay 10 times automatically. It measures action release timing and response consistency to ensure the relay won't fail under real-world driving conditions.
- Automated rapid cycling
- Consistent timing measurement
- Green/Red pass/fail indicator
Real-Time Digital Screen
The LED digital screen displays battery voltage from 11V to 25V the moment you connect. It works for both 12V cars and 24V heavy-duty commercial vehicles.
- Dual voltage 12V/24V support
- Bright LED digital readout
- Monitor battery health live
Universal 4-Pin & 5-Pin Support
Equipped with two dedicated relay sockets and a gear selector switch. It handles standard automotive relays for cars, vans, and light trucks with one tool.
- Integrated one-piece design
- Silicone alligator clips
- No internal batteries required
Diagnose like a pro,even with no experience
Clip to Battery
Connect the silicone clips (red to positive, black to negative). The tool powers up instantly and shows battery voltage.
Insert & Select
Plug your relay into the 4-pin or 5-pin socket and adjust the selector switch to match.

"Found a bad fuel pump relay in 30 seconds that had been driving me crazy for weeks. The 10-cycle test caught it sticking after the 4th cycle. Amazing tool."
