## Questions & Answers

**Q: Can you ground these to anything like your truck? A bolt ect**
A: Yes. Any metal that is attached to the frame. It should be cleaned with sandpaper or a wire brush first before you attempt to ground it.

**Q: Will this work well on positive ground 6 volt vehicles on do you have a netter tool**
A: If you can hold the prong on the “positive ground” and somehow make a contact from an alligator clip to the wire you are trying to test... then yes. But definitely that’s a huge flaw of that device.

**Q: Does the screen update quick enough to read codes with obd1? the obd1 flashes power to the tester will it register the "flash"?**
A: It’s not designed for that

**Q: I purchased several test light assemblies, I am looking for the replacement electrical mechanism.**
A: This one is very nice.
