Sup everyone, so I bought my Mustang off of someone about 5 months ago. The guy got me for sure when I test drove it everything was working fine. Long story short I have had to put in a lot of money to fix it up. One of the problems I have yet to figure out though is the battery light, it keeps turning on and off. With that being said the car has never turned off on me. The battery light just pops up randomly and it is becoming more frequent. I drive a 2005 V6 4.0L Mustang and it has 101,000 miles on it. I took it to Autozone and got the battery and alternator tested. Both passed and showed no problems. I also checked the fuse box and everything with that is fine. I am going to be checking the ground cables to see if anything is loose or shorted out. What am I missing here? Any help is appreciated, thanks.
