Hadi,

All of the common tests to isolate the fault have been covered, except for a possible excessive load problem. However, the alternator should be able to charge the battery at idle in normal circumstances, even at idle.

So, if at idle the (VOM) readings across the battery terminals are less than about 14.x (cold) or 13.7+ warm/charged, you may have a load problem IF the regulator is working...And that is the question.

My bet is the regulator is bad. If you're not comfortable with the mechanics of checking it out yourself, then let an auto repair shop diagnose it for ya.

Don't over-think this. Chances are it is quite simple (and I'll bet on the regulator - other data not withstanding).
