Automotive Circuit Fault Probe Tester, 20A 48V Parasitic Draw Tester for Car Fuse Circuits, Inline Current Monitor with Overcurrent Detection, Mini & Standard Blade Fuse Compatible
🔋 Locate the Exact Fuse Causing Battery Drain: Stop guessing which circuit is draining your battery. This tester allows you to pinpoint the specific fuse responsible for abnormal parasitic current draw—fast, accurate, and without disconnecting the battery.
🔎 Direct Fuse-Level Current Analysis: Test individual fuse circuits in real time and observe actual load behavior under operating conditions. Instantly identify which circuit is drawing abnormal current without removing the battery connection.
📊 Stable & Accurate Real-Time Current Measurement: Measures 0.01A–20A current with clear real-time display. Provides reliable data for diagnosing parasitic drain, circuit overload, and abnormal electrical behavior.
⚡ Easier Than Using a Multimeter: No loose probes or unstable contacts. Simply plug into the fuse slot to get steady real-time current readings without disconnecting the battery.
🛡Maintains Factory Circuit Protection: The fuse-inline design measures current through the vehicle's original fuse, keeping factory circuit protection active while monitoring current during diagnostics.
