## Questions & Answers

**Q: why does the light alternate between yellow and green?**
A: I have the same issue. The alternating lights  never stop. I suspect damage, although it will start a dead car battery

**Q: When we hook this up to my dirtbike, it alternates between yellow and green and makes a beeping noise. Any idea why?**
A: When it is yellow, that means the battery is not fully charged. When the light turns green, the battery is fully charged

**Q: En qué tiempo carga una batería**
A: yes it can --this is a very good product

**Q: Why won't the lights on the charger come on when i connect it to my car battery or my motorcycle battery**
A: Assuming the unit is properly plugged in to a working electrical outlet on the other end, you should be getting some kind of light, even a dead battery or reverse polarity connection would show a red fault indicator.
