Multifunctional Detection Modes

• Polarity & Voltage Test: Used to determine the positive and negative poles of the circuit. 
• Continuity Test: Efficiently detect broken wires, faulty switches, or open circuits.
• Short Circuit Tracing & Locating: Pinpoint shorted components or wiring faults accurately.
• Ground Test & Jumper Function: Verify grounding integrity and simulate power delivery for diagnostics.
• Diode Test: Check diode functionality within vehicle circuits.
• Quick Self-Test: Confirm the tester’s own operational status before use.

Efficient Component Activation

Activate key vehicle components directly through the tester—ideal for real-time diagnostics:

• Fuel pumps
• Headlights
• Solenoid valves
• Blower motors
• Cooling fans

Activation current range: 0–8A, enabling realistic load simulation without external power sources.

Practical & Safe Design

• High-quality stainless steel probes with insulated handles for user safety
• 5-meter (16.4 ft) test cable—covers full vehicle reach from engine bay to rear lights
• Clear LED indicators + audible alerts for instant feedback
• Digital display for precise voltage readings in all lighting conditions
• Overload protection: Auto-trips at >8A with alarm signal to prevent damage

Wide Application Compatibility

Works with all standard 6V–24V automotive electrical systems, including:

• Cars & SUVs
• Pickup trucks
• Motorcycles
• Engineering/construction vehicles
• Marine vessels (boats)

Ideal for trailer light testing, wiring harness validation, and general electrical system troubleshooting.
