Product Overview
When a window, light, relay, fan, or accessory stops working, guessing at parts gets expensive. This powered test probe helps trace whether the circuit has voltage, ground, continuity, or a failed component so the repair starts with evidence.
It is a general electrical diagnostic tool, not a scan tool and not a substitute for the vehicle wiring diagram. Confirm the tool's stated voltage range, lead length, fuse protection, and included accessories before applying power or ground to any circuit.
Key Features & Performance
- Digital display for fast circuit readings
- Polarity and continuity checks at the probe tip
- Can apply power or ground to suitable low-voltage components
- Long lead supports testing around cars, trucks, trailers, and equipment
Common Uses
- Finding a broken power or ground path
- Bench-testing a compatible motor, lamp, relay, or solenoid
- Checking trailer wiring and accessory circuits
Technical Specifications
- Product Type: Powered automotive circuit tester
- Display: Digital
- Connection: Battery-powered test leads
- Application: Low-voltage vehicle electrical diagnosis
Installation & Fitment
- Read the included instructions before first use
- Connect to a known good battery source with correct polarity
- Verify operation on a known circuit
- Never power airbag, control-module, data-bus, or unknown circuits
- Use a wiring diagram and fused procedures for sensitive electronics
Compatibility Notice
This is a universal or service item, not a guaranteed fit for every vehicle, machine, or job. Measure and compare all dimensions, connections, operating limits, and the intended system before purchase. Custom installation or professional setup may be required.
Frequently Asked Questions
Q: Can this tell me why an accessory stopped working? A: It can show whether voltage or ground is missing, helping narrow the fault to wiring, a switch, relay, fuse, connector, or component.
Q: Is it the same as an OBD scan tool? A: No. It tests electrical circuits directly and does not read vehicle diagnostic codes.
Q: Can I send power into any wire? A: No. Applying power to a signal, module, airbag, or data circuit can cause damage. Identify the circuit first.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
