Automotive Circuit Tester 0.01A–19.99A

This battery-powered probe measures DC current from 0.01A to 19.99A to help locate parasitic drains and faulty modules in vehicle electrical systems. It is intended for technicians and DIY owners who need to verify circuit health without removing the battery.

Non-slip ABS/PC body with rubber coating

The tester housing uses non-slip ABS/PC material with an outer rubber coating and reliable internal components rated for 0°C–40°C operation. An integrated front light illuminates dark workspaces while the LCD shows current value and polarity, and medium and small fuse adapters plug directly into the fuse socket for hands-free testing.

Medium and small fuse adapters included

Two plug sizes are supplied so the tool fits standard blade fuse blocks without extra parts. The package also includes the instruction manual that explains the fuse-swap procedure and the 10-second maximum load limit at 20A 48V.

Questions about this item

What current range and voltage limit does the 0.01A-19.99A tester handle?

It measures DC current from 0.01A up to 19.99A and is rated for a maximum load of 20A at 48V for no longer than 10 seconds.

What are the overall dimensions of the tester housing?

The unit measures 9.84 inches long by 5.98 inches wide by 1.38 inches high, making it compact enough for a tool bag or glovebox.

How do you connect the tester to a vehicle circuit, and what step is often missed?

Remove the supplied blade fuse from the tester, pull the vehicle's fuse from its circuit, insert that fuse into the tester socket, then plug the tester into the empty fuse slot; the step often missed is reinstalling the vehicle's original fuse into the tester before measuring.
