Innova PowerCheck Circuit Testers

Innova PowerCheck circuit testers are multi-functional, powered electrical diagnostic tools designed for 6 V, 12 V, and 24 V automotive systems. They allow mechanics and DIYers to test circuits, check voltage, and manually apply power or ground directly to components to verify if they work.

Key features:

* Supply power for accurate testing: Apply 3 V, 5 V, 12 V, or 24 V directly to circuits or components to simulate real-world conditions and isolate faulty parts
* Versatile electrical testing: Run fuse tests, circuit tests, component activation, battery checks, ground verification, and relay diagnostics—all in one tool
* Built-in 10 MegOhm circuit breaker: Protects your circuits and the tool itself from overload, ensuring safe operation while maintaining high sensitivity
* 20-ft. heavy-duty cable: Extended reach for easy testing across larger vehicles or workspaces without relocating the unit
* Diagnose by activation: Actively power components to see if they respond as expected—quickly pinpoint what's working and what needs replacement
* Large 1.25 in. backlit LCD screen: Bright and readable in any lighting condition. View real-time feedback on tests and component behavior clearly and instantly
* 10 MegOhm input impedance: Prevents damage to sensitive automotive systems, including ECU protection
* Power and ground with circuit breaker protection: Deliver power or ground directly to the component while staying protected by the integrated breaker system
* Positive / Negative LED indicators: Quickly identify power polarity to avoid mistakes and simplify troubleshooting
* Automotive uses include: Diagnosing car fuses, relays, grounds, power circuits, batteries, and electrical components with confidence
* Household uses include: Checking general circuits, small appliances, DIY electronics, and more with pro-grade precision
