I have a 2001 Nissan Maxima v6 I was driving the other day and my brake light and battery light came on I continue to drive to get home all the lights turned off drove fine for about 5 minutes then ABS light would start flashing air bag light was flashing overdrive was flashing and turning on and off I replace the alternator about six to eight months ago it currently has 10000 miles on it so I don't think its the alternator because I had different problems and when I tested my battery after driving about 15 miles the battery still at 12 volts amd everything was still acting up and barely running. Once I turn the car off it would not turn back on without a jump but the battery still had 12 volts so it would be greatly appreciated
