With the engine running it should be 14.2 volts, take you car to an electrician, he wont charge you to test the battery and alternator. A mechanic with a code reader can remove the warning light if it stays on after the problem is fixed. Good luck

it may have deffective diode on the charging system(the alternator). 14 volts is an over charge in a battery. ampere reading must be on what the battery designed.

Battery light still on after new battery and alternator fitted


Use a volt meter and make sure the battery has 11 volts or better. If not the battery does need replacing. Anything under 11 volts tells you the battery is no good to use any longer and will not hold a charge
