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..

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.
