Handheld automotive circuit probe tester with alligator clip and colour digital display

Power Circuit Probe Tester 9V-30V 0.3V-70V 10 functions

SKU CH-NVWJ-CDQBT

Tests 9V-30V automotive circuits with 10 functions covering voltage, resistance, diode, continuity and component activation from .3V to 70V

  • Team affiliation1 Piece
  • Key featuresAutomotive Circuit Tester Body with Alligator Clip, DC, fals
  • Triple-mode operation covers voltage, resistance and diode tests
  • 10 functions replace test lights, multimeters and fuse testers
  • Component activation drives lights, fans and fuel injectors safely
  • Voltage range from .3 V up to 70 V for wide diagnostics
  • Powered by vehicle supply between 9 V and 30 V

Professional-Grade Triple Mode Tester

This automotive circuit tester switches between Voltage, Resistance, and Diode Modes with one-touch operation. It delivers over 10 testing functions through a colour digital display for efficient diagnostics. The tool suits professional garages, driveway mechanics, and DIY enthusiasts working on vehicle electrical systems. It replaces several separate instruments for streamlined troubleshooting.

Alligator Clip and Component Activation

The tester body includes an alligator clip for secure grounding during measurements. A Component Activation function supplies a safe low-voltage signal when the "+" button is pressed while connected to power. This activates lights, fans, wipers, and fuel injectors to verify part functionality before replacement. The feature saves time and prevents unnecessary component swaps during repairs.

0.3V-70V Range for 9V-30V Systems

The voltage measurement span covers .3 to 70 volts for continuity and resistance checks across low-voltage circuits. It comfortably handles standard 9V to 30V automotive electrical architectures found in most passenger vehicles. The tester runs out of headroom on high-voltage hybrid or electric vehicle propulsion systems exceeding the stated maximum. It is not for diagnosing high-voltage battery packs or traction inverters.

Questions about this item

What maintenance or replacement will the probe tips and alligator clip need later?

The probe tips and alligator clip are consumable contacts; replace them when they show pitting, corrosion or looseness to keep readings accurate.

What limit appears first during sustained use of the 9V-30V circuit tester?

Continuous component activation can heat the probe body; the duty cycle is limited by thermal protection, so pause between long tests.

How much heat or noise does the tester produce when running all day?

The unit is silent with no fan; only mild warmth develops at the probe tip during extended voltage or resistance measurements.
