My 07 gxp is starting to act up. I was leaving a friends house tonight, started driving down the road and charging system faliure pops up on the info center. I looked at the volts and they were falling from about 15 but steadied out at around 14. I turned the car off checked conections and everything looked fine, and the car started back up with no problems. I drove home and the volts were at 14.30 most of the trip and then fell down to 13.87. I just replaced the battery about 4 weeks ago so im hoping that its not the battery again.

Anyone else have this happen to them, or any ideas whats going on?

Thanks

How many miles are on the car?


You may have a bad alternator.

My only next guess is to check your alt.

You've got plenty of voltage, so alt. is good. Check your grounds, Ive heard of bad cabling on these cars as well, more than likely the problem.

your voltage sounds a bit high, I would suspect the battery has a high internal resistance or you are looking at loose/corroded cable(s). Beyond that, a failed diode bridge in the alternator could be the culprit, but I very much doubt it. Since you had the battery replaced, I would look at the cables first.
