Questions about this product
- Will this tester work on my car's relays?
- This tool works with standard 4-pin and 5-pin automotive relays. It requires a vehicle battery voltage between 11V and 25V to power up and run the diagnosis. It won't work with other pin configurations or systems outside this voltage range.
- What happens if I accidentally connect the clamps to the wrong battery terminals?
- You do not need to worry about damaging the unit. It comes with integrated reverse polarity protection to prevent damage from incorrect connections. It also features built-in overload protection to keep your testing safe.
- How does this tool actually test and show if a relay is working?
- First, connect the clamps to your 11-25V vehicle battery to power the device. The tester then automatically runs a 10-cycle test on the relay's coil and contact functionality. Once finished, a clear LED indicator lights up to show a pass or fail status.
