Hey guys I have 2004 Infiniti G35 coupe, and the light for some reason want to keep coming on and off. And the key isn't in the ignition. I watch my charger volt come up and go right back down. The battery is brand new and alternator as well. I am stump can any help out on this one.

 

Is this happening even when the car is off?

 

Yeah, it was really weird so I changed batteries, cause I've been performance mechanic for 10 years lol. And that fixed it. It turns out I had a bad cell in the old battery. Well thanks AutoZone for that one 🙄🙄🙄🙄
