{"product_id":"the-circuit-cartographer-automotive-power-circuit-tester","title":"The Circuit Cartographer | Automotive Power Circuit Tester, 12V\/24V","description":"\u003cdiv class=\"product-narrative\"\u003e\n\u003cp\u003eElectricity Does Not Announce Itself. A shorted harness, a corroded ground, a relay that only fails once it is warm. Faults like these consume hours with a multimeter, because a meter reports a value without telling you where the circuit went wrong. The PowerScan PS100 answers the real question. It identifies positive, negative and open circuit instantly, and it traces a short to the physical place it occurs.\u003c\/p\u003e\n\u003cp\u003eBuilt around the diagnostic workflow. Read voltage, current and resistance at the fingertip, check continuity across switches, relays and diodes without dismantling anything, and confirm a bad ground contact in seconds instead of after a lap of the vehicle. Relay component testing happens in circuit, and the unit runs from the vehicle battery at 12 or 24 volts, so there is no internal cell to charge before a job.\u003c\/p\u003e\n\u003cp\u003eProtection included. A circuit-breaker-protected input means an accidental probe across a live circuit ends with a reset rather than a repair bill. The TFT colour display at 160 x 128 dpi keeps a numeric readout legible in workshop light, and the analogue display behaviour turns a fluctuating signal into visible movement rather than a blur of changing digits.\u003c\/p\u003e\n\u003cp\u003eA tool for the diagnostic bay rather than a component for the toolbox. The kit arrives with the carrying case, clamps and probes needed on the first day, so it is a complete instrument rather than something you then have to accessorise before it can be used.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eAny meter can measure a circuit.
