Guys I have a 2004 Mazda Axela. My battery
light came on while driving. Did a voltage test
on it found out that the alternator is not
charging the battery. Did a code test, got this
code P2503, charging system voltage low. Did
further testing then found out that two pins in
the PCM is sending the wrong volts to the
alternator causing damage
