- ONE TOOL FOR FASTER TROUBLESHOOTING — This automotive circuit tester combines a power circuit probe with AC/DC voltage, polarity, resistance/continuity and diode checks. It also supports wire tracing and component activation, helping you check power, ground and circuit condition with fewer tools.
- FIND ELECTRICAL FAULTS FASTER — Use live voltage readings, continuity checks and the built-in wire tracer to narrow down the issue. Find short circuits, open circuits, bad grounds and damaged wiring more efficiently, without working through the entire harness step by step.
- TEST BEFORE YOU REPLACE — Use component activation to test compatible relays, fuel pumps, cooling fans, blower motors, bulbs and other vehicle components. Check whether the part responds before buying a replacement, helping you determine whether the issue is in the component or the circuit.
- TROUBLESHOOT TRAILER LIGHTS WITH EASE — Use KM06 as a trailer light tester to check voltage, ground, brake lights, turn signals, connectors and trailer wiring on work trailers, campers and RVs. Wire tracing helps you narrow down the fault before replacing parts.
- BUILT FOR 8–35V VEHICLE ELECTRICAL WORK — Designed for 8–35V automotive electrical systems across cars, trucks, RVs and trailers. Auto-reset circuit protection helps guard against overloads, while the sunlight-readable TFT display, red/green indicators, tone alerts and LED flashlight keep results clear in the garage or at the roadside.
