XENIVO

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

XENIVO

$15.99

More Details
Main highlights
- 🛡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.
- 🔎 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.
- 🔋 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.
- 📊 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.

Power Probe

$144.46

More Details
Main highlights
- Read current on all most common fuses from 1A to 80A.
- Quickly identify parasitic draw by probing each fuse on the fuse panel. The tool displays green for inactive, yellow for active, and red for open. Move on if you see green and stop when you find an active or open circuit.
- Isolate and locate parasitic draw by finding current flow on fuses
- If the tips wear out or break, simply replace them and continue working.
- Displays live current in amps, allowing you to diagnose parasitic draw without removing the fuse or triggering module resets.
