Frequently Asked Questions

Will this tester damage sensitive computer modules (ECU)?
No. The internal current-limiting system and integrated circuit breaker safeguard sensitive vehicle electronics during testing.
Can I use this on both 12V cars and 24V trucks?
Yes! It automatically works across any direct current (DC) system between 6V and 24V, including cars, trucks, boats, and trailers.
How does it indicate positive vs negative polarity?
When probing positive voltage, the indicator lights red. When connected to negative ground, it turns green for instant visual clarity.
