Hey man i could really use an answer very similar, same code 2503. The car keeps draining the battery dead put new battery in and new alternater and it continued to fail. I then complained about alternater and had it replaced with another new one from another company and same issue. They ran a a test charging test on the car and it shows batter fine but its shows up as alternator 0 voltage basically none existent. Im losing hope that i can figure this one out. any advice would be appreciated
