Autel PowerScan PS100 Circuit Tester 12V/24V Electrical Diagnostic Tool

Find electrical faults faster and stop guessing. The Autel PowerScan PS100 gives you direct control over your vehicle’s circuits, so you can diagnose problems with clarity and fix them without delays.

From testing voltage to activating components on the spot, it turns complex electrical troubleshooting into a straightforward process you can handle with confidence.

Pinpoint faults and test circuits with total control

✅ Identify shorts, bad grounds, and open circuits quickly to avoid wasted time

✅ Read voltage with 0.1V resolution for clearer, more accurate diagnostics

✅ Activate components instantly to confirm if parts are working

✅ Test across full 12V–24V systems for cars, trucks, and trailers

✅ Reach every corner with 20ft cable plus 20ft extension for large vehicles

✅ Work day or night with backlit LCD screen and built-in lighting

✅ Detect polarity instantly using LED indicators and audible alerts

The PS100 connects directly to your vehicle battery, giving you immediate access to electrical diagnostics. You can check voltage, resistance, and continuity, or send power to components like fans, relays, and lights to verify performance on the spot.

Its four working modes—DC voltage, AC voltage, resistance, and tone—make it easy to switch between tests without extra tools. The clear LCD screen shows precise readings, while the tone function helps you identify results even in low-visibility environments.

The built-in 10 Amp circuit breaker protects both the tool and your vehicle from overload. A quick self-test ensures everything is working before you begin, so you stay in control from start to finish.

Compared to basic testers, this tool combines measurement and activation in one unit. That means fewer steps, less guesswork, and faster diagnostics whether you're working in your garage or on a larger vehicle setup.
