Default 2012 Honda Civic EX - Alternator only charges when headlights are ON

Hello all,

My Honda civic 2012 EX's alternator only works when the headlines are ON.

Voltmeter said my battery is 12.4 V. I turned on the car with headlights OFF, it's still 12.4 V (indication of alternator NOT charging/working).

But as soon as I turn ON the headlights, I get 14.5 V.

Has anyone seen this before? and what did you do to resolve this issue?

Thanks for your help.
