About This

• 【8 Diagnostic Modes for Circuit, Signal and Battery Testing】The KM601 automotive circuit probe tester combines eight diagnostic modes into one handheld unit: oscilloscope waveform analysis, power circuit testing, fuel injector signal measurement, relay operation verification, component activation, battery system evaluation, continuity and polarity checks, and short circuit detection. It performs over twenty essential electrical tests used in daily diagnostics. Supports 8–35V systems across cars, trucks, motorcycles, RVs, and marine equipment. A practical gift for anyone who works on their own vehicles or handles professional electrical repairs
• 【Fuel Injector Tester with Waveform and Numeric Display】Misfires and rough idle do not always indicate a faulty injector. This fuel injector tester measures control signals up to 0–260V with pulse width from 0–25 ms, displaying waveform and numeric data together. Verify whether the ECU command reaches the injector before ordering replacement parts or opening the wiring harness. The wire tracer automotive function helps follow injector circuits through the harness without unnecessary disassembly. A useful gift for DIY mechanics who want to diagnose engine issues with clear data
• 【Built-In Battery Diagnostic Tool for 12V Systems】Intermittent no-start complaints are difficult to reproduce in the shop. The integrated battery diagnostic tool automatically checks battery health, cranking performance, and charging status. Compatible with Flooded, AGM, GEL, and EFB battery types. Identifies weak batteries, voltage drops, and charging issues on cars, trucks, and motorcycles without requiring a separate tester. Covers both 12V passenger vehicles and 24V commercial truck electrical systems within the 8–35V range. A reliable gift for the DIYer who maintains multiple vehicles
• 【Component Activation and Short Circuit Finder】Apply power or ground directly from the probe to test relays, fans, fuel pumps, solenoids, lights, and motors. No jumper wires or external battery packs required. The short circuit finder function helps locate faults faster during testing. Built-in circuit protection safeguards the tool and vehicle when tracing shorts or applying current. The 30ft cable reaches from the battery to the rear of long trucks, RVs, and trailers without repositioning the connection point. A solid gift idea for Father's Day that saves time on electrical repairs
• 【Professional Kit with 30ft Cable, Carry Case and Warranty Support】The kit includes the circuit probe tester, 30ft cable, durable carry case, and replaceable fuse. The extended cable reaches from the battery to the rear of trucks, RVs, and trailers without repositioning the connection point. A replaceable fuse is included for maintenance. The carry case stores the unit and accessories for transport between job sites. ✔12-Month Warranty, ✔30-Day Hassle-Free Returns, ✔Lifetime Tech Support from real humans. Have questions?
