Inductor Tester – Motherboard Coil Fault Detector Tool
Inductor Tester – Motherboard Coil Fault Detector Tool
Inductor Tester & Motherboard Coil Fault Detector
Diagnose faulty inductors on PC and mobile phone motherboards in seconds — no disassembly required. This compact electromagnetic induction tester uses a precision sensor probe and a clear green LED indicator to instantly confirm whether a coil is functioning normally. Simply press the TEST button, hover the probe over the inductor, and the LED tells you the result right away. Perfect for electronics repair technicians and DIY enthusiasts who need a fast, reliable, non-invasive way to check motherboard coils.
Key Features
- Electromagnetic Induction Detection: Locates inductor faults without disassembly, dramatically speeding up the repair process.
- Instant Green LED Feedback: LED illuminates when the inductor is working normally; no light means a fault is detected — eliminating guesswork and misdiagnosis.
- One-Touch Operation: Long-press the TEST button to activate; compact pen-style design (82 × 22 mm) fits comfortably in hand and a tool bag.
- High Precision & Stability: Professional-grade detection circuitry for accurate, repeatable results on mobile phone and computer motherboards.
- Dual Power Options: Compatible with a CR2032 button cell battery OR USB Type-C power — use it at your bench or on the go.

Frequently Asked Questions
Q: What types of motherboards is this inductor tester compatible with?
A: The inductor tester is compatible with a wide range of electronic motherboards, including desktop PC motherboards, laptop motherboards, and mobile phone circuit boards. Any board that uses standard surface-mount or through-hole inductor coils can be tested with this tool.
Q: Does the tester come with a battery?
A: No, a battery is not included. The tester supports two power options: a CR2032 coin cell battery (purchased separately) or USB Type-C power for convenient bench use.
Q: Do I need to remove the inductor from the board to test it?
A: No disassembly is needed. The electromagnetic induction probe detects the coil's status while it remains mounted on the motherboard, making diagnosis faster and reducing the risk of damaging surrounding components.
Q: How do I interpret the LED result?
A: When you hold the TEST button and bring the probe near an inductor, a green LED that lights up confirms the inductor is operating normally. If the LED does not illuminate, the inductor is likely faulty and should be inspected or replaced.
