## Questions & Answers

**Q: How can i exchange this item mine is not working**
A: Put it in the trash and leave feedback so other don't make the same mistake as we did.  I would never recommend this item to anyone!  Mine stopped working too, waste of money...

**Q: If i use this tool to check a 24v dc circuit how much current will it draw?  my goal is something around 1amp at 24 volts.**
A: It depends on what system you checking some starter systems drive to 160 A

**Q: Ho long does it take for display to indicate voltage?**
A: If your connected to a proper ground such as the negative post of the battery it should be immediately

**Q: Does the tester have a visible light?  I need to test pulsing ignition circuits and a digital meter alone would be too slow to react.**
A: It does not have a pulsing light. The digital readout lights up, then shows voltage. Although you could go off of the screen lighting up, but i'm not sure how accurate that would be.
