Master kit combining Power Probe 4 with the PPECT3000 and accessories to cover component activation, circuit checks and fault tracing—built for faster electrical diagnostics on modern vehicles. Power Probe 4 supplies power or ground for functional component testing on or off the vehicle, helping you test motors, lights, relays, sensors and fuel injector circuits from a single handheld tool. Advanced signal diagnostics: multiple DC voltage readings on one display plus ohmmeter feedback, continuity and bad ground indication; includes AC-RMS, peak-to-peak, frequency and pulse width indicators for signal testing. Built-in protection and pro features: self-resetting thermal 8 amp circuit breaker, 12–24V operating range, 23 ft power cable, PCM/ECM driver for safer computer driver circuit testing, and PPECT mode for open-circuit signal detection (when used with compatible tracers). PPECT3000 helps trace short and open circuits without removing trim—find shorts to ground, breaks and intermittent conditions with sensitivity adjustment (1–8 in / 3–20 cm) plus visual navigation and sound indicators; works across cars, boats, RVs, trucks and trailers., Weight: 5.4 pounds, Manufacturer: cellhelmet
