Power Probe 3-Circuit Tester Kit for 12–24V Vehicles, Red — Built-in Voltmeter, 20 ft Cable & Case

The Power Probe PP319FTCRED is a portable 3-circuit tester kit that supplies power or ground, measures voltage, and helps diagnose 12–24V automotive and equipment electrical systems.

Designed for mechanics, electricians, and DIYers who work on vehicles, trucks, RVs, and off-grid equipment, this compact kit combines a three-circuit power probe, continuity and component testing features, and a built-in voltmeter into a single, transportable package. The kit ships with a durable storage case and accessories so you can test components, chase shorts, and confirm grounding quickly without swapping multiple tools.

How does this tester help pinpoint electrical faults?

The Power Probe provides live power or ground on demand and shows system voltage with DC voltmeter indicators, allowing you to stimulate connectors and verify circuit responses. Use it to isolate open wires, verify component function, and locate shorts by carefully applying power or ground through the probe tip.

• Supply or remove 12–24V power/ground for component activation
• Continuity tester mode to check wire and fuse integrity
• Built-in voltmeter LEDs for immediate voltage feedback
• Resettable 8A circuit breaker protects probe and vehicle circuits

What accessories and cable length does the kit include?

The kit includes a selection of leads and adapter clips stored in a fitted case so you can get to work fast. A long power cable provides reach for larger vehicles or equipment, so you won’t be limited by proximity to the battery during diagnostic procedures.

• 20-foot power cable for extended reach around trucks or machinery
• Adapters and clips for common connector types and test points
• Protective storage case to organize tools and prevent damage
• Compact probe body that fits in tight engine bays

How safe and durable is the Power Probe during testing?

Safety features reduce the risk of damage to the tester and vehicle circuits during normal diagnostic use. The resettable 8 amp circuit breaker interrupts excessive current, and the probe’s robust construction is built for workshop use and repeated handling.

• Resettable 8A breaker to prevent overloads during activation
• Rugged housing designed for routine shop and field use
• Clear LED voltmeter display for on-contact voltage verification
• Accessory fittings help avoid improvised or unsafe connections

What systems and voltages is this tester compatible with?

The PP319FTCRED operates across standard vehicle and equipment DC systems, covering most automotive, marine, RV, and industrial 12–24V applications. It’s built to work on common electrical architectures without requiring additional converters.

• Works on 12V and 24V DC systems—cars, trucks, RVs, and some equipment
• Suitable for testing sensors, actuators, relays, and wiring harnesses
• Use as a component tester, continuity checker, and power source
• No external power supply required beyond the vehicle or equipment battery

Who this is for: The Power Probe PP319FTCRED is ideal for professional technicians, mobile mechanics, fleet maintenance teams, and informed DIYers who need a single, reliable tool to diagnose DC electrical problems quickly. If you regularly test switches, relays, sensors, fuses, or wiring in 12–24V systems and value portability, a built-in voltmeter, and overload protection, this kit adds targeted diagnostic capability to your toolkit.
