Hello 👋 everyone..

show my battery light is on, I check the battery with a meter, and reeds 12. something, I started the engine and checked it again and It read 14. something volts I’m assuming the alternator is in good shape! what does this mean if my battery reads 12 V and with the engine on reads 14. Does anybody have any answers please..

The alternator is probably not in good shape... It should be checked to see if it is operating correctly.

Take your car, to any auto parts store. Have them preform, a load test. On your charging system.

12.x V and 14 V on sounds like a normally operating system.

But as noted auto parts stores usually have the proper equipment to check/verify.

The light usually means the 12 V is not being charged properly. If the voltages are 12.x V engine off and 12.x V engine running that usually sets the light on. Normally with engine on one would expect 13 V - 15 V.

Unless I'm missing something, shouldn't jzchen be spot on? When I test alternators I look for 14 volts at idle, which sounds like the case here.

The auto parts store test should shine a light on what's broken, hopefully.
