Power Probe 3 Circuit Tester Kit PPKIT03S with ECT3000 Short-Finder — 12V power & LED receiver

The Power Probe 3 Circuit Tester with ECT3000 Short-Finder (PPKIT03S) is a handheld diagnostic kit that powers components, traces shorts and opens, and lights your work area for faster electrical troubleshooting.

Mechanics, electricians, and DIYers often need a compact, accurate tool to locate shorts and verify circuit integrity without removing panels or guessing wire paths. The PPkit03S combines a Power Probe 3 power/voltage tester with the ECT3000 short-finder receiver so you can energize a circuit, follow a distance-indicating signal, and illuminate tight spaces. It’s built to be practical on cars, trucks, boats, ATVs, and light industrial equipment.

How does this kit help me find shorts and open circuits?

The ECT3000 receiver reads a pulsed signal sent through the wiring and uses a signal distance bar to indicate how close the fault is to the probe. Instead of testing each junction manually, you can scan along harnesses and panels until the receiver shows a high signal strength, narrowing down the location quickly. This reduces time spent dismantling and guessing.

• Signal distance bar shows relative distance from short or open
• Pulsed tracing avoids continuous load on circuits while locating faults
• Works on insulated wiring—trace without cutting insulation

What functions does the Power Probe 3 provide on the job?

The Power Probe 3 in this kit supplies switched power, measures voltage and ground, and lets you activate components safely for functional testing. It’s a multipurpose probe that replaces multiple tools during diagnostic procedures and speeds up verification of switches, relays, motors, and lights. The tool’s controls are designed for single-handed operation in cramped engine bays.

• Delivers switched 12V power to activate components directly
• Voltage measurement capability for quick checks of circuit health
• Ergonomic probe layout for controlled, single-handed use

How does the kit improve visibility and accuracy in tight spaces?

The ECT3000 receiver includes an integrated LED that illuminates the work area while you trace wiring or inspect connectors. Better lighting helps you avoid misreading signal strength or overlooking damaged insulation. Coupled with the probe’s precision tip, the kit reduces false leads and speeds up accurate diagnostics.

• LED light on receiver brightens dark engine bays and underdash areas
• Precision probe tip accesses small terminals and connector pins
• Compact receiver design for working in confined spaces

Who is this for? The Power Probe 3 Circuit Tester with ECT3000 Short-Finder (model PPKIT03S) is aimed at professional technicians and serious hobbyists who need a durable, all-in-one electrical troubleshooting solution. If you regularly diagnose wiring faults, test components in-place, or want to reduce guesswork and teardown time, this kit streamlines those tasks. It’s suitable for automotive, marine, powersports, and light equipment electrical work where speed, accuracy, and the ability to trace a fault without cutting wires are priorities.
