XENIVO Parasitic Draw Tester — Automotive Circuit Fault Probe Tester, 0.01–20A, Mini & Standard Blade Compatible

The XENIVO Automotive Circuit Fault Probe Tester is an inline fuse monitor that measures 0.01–20A in real time to locate parasitic battery drains and detect overcurrent while preserving factory fuse protection.

If your vehicle battery is dying overnight or a circuit behaves inconsistently, this compact inline tester plugs into mini and standard blade fuse slots to show live current flow without disconnecting the battery. Designed for technicians and DIYers, it replaces guesswork with a clear numeric readout and built-in overcurrent detection so you can identify the offending circuit quickly while keeping the original fuse in place.

How does this tool find which fuse circuit is draining my battery?

The tester reads the electrical current passing through the existing fuse, enabling you to check each fuse one by one until you spot an abnormal draw. Because it operates inline, you don’t have to remove the battery or interrupt other systems; simply insert the tester into a fuse slot and observe the real-time value.

• Measures currents from 0.01A to 20A for detecting low parasitic drains.
• Works with both mini and standard blade fuses for most vehicles.
• Maintains factory fuse protection while monitoring load.
• Plug-and-read operation avoids loose probes and unstable contacts.

What safety features stop me from blowing fuses or damaging circuits?

The device is designed to use the vehicle’s installed fuse, so the original circuit protection remains active while you test. It also includes overcurrent detection so you can see if a circuit is exceeding expected current levels before component damage occurs.

• Inline design preserves factory fuse protection during diagnostics.
• Overcurrent alert signals when measured current nears or exceeds safe limits.
• Clear readout helps you react quickly if a spike appears.

How accurate and stable are the readings compared to a multimeter?

The XENIVO tester delivers steady, drift-free measurements optimized for fuse-level diagnostics, avoiding the unstable contacts and probe handling required by multimeters. Its resolution and range make it suitable for spotting very small parasitic draws as well as heavier loads up to 20A.

• Real-time numeric display with stable readings under load.
• 0.01A resolution helps identify subtle parasitic currents.
• Better contact reliability than loose multimeter probes in fuse boxes.

Can I use this tester on different vehicles and fuse types?

Yes — the unit supports both mini and standard blade fuses, covering most modern cars, trucks, and SUVs. Its compact size fits into crowded fuse panels, and the straightforward plug-in method makes it quick to move from one fuse slot to another during a diagnostic session.

• Compatible with standard and mini blade fuse sizes.
• Compact form factor fits tight engine bay and dash fuse boxes.
• Portable and simple to swap between circuits for systematic testing.

Who this is for: Automotive technicians, electrical troubleshooting enthusiasts, and vehicle owners who want a faster, safer way to track down battery drains and circuit faults. If you need precise inline current measurements without interrupting factory protections — whether diagnosing overnight battery drain, checking aftermarket accessories, or validating repairs — the XENIVO tester provides clear, repeatable data you can act on.
