For the past two days, the battery indicator on the dashboard showing less than 13 almost to the red area zone
Even when I hit the gas

possibly the voltage regulator

Shamil · 12-14-2007, 03:59 AM

where to find this regulator

The alternator should be internally regulated. Not sure how hard parts are to come by where you are at, but I would suggest having the alternator checked.

The voltage regulator is inside the alternator. And it's function is to keep the voltage from gong too high. If your voltage is too low, it is more likely a rectifier inside the alternator that is bad. But I would check a few other things first.

What is the condition of the belt that drives the alternator? Is it tight? Are all the electrical connections clean and tight? Are you sure the battery is good, no dead cells? If you have a good auto parts store close by, they can load test both the battery and the alternator to make sure they are working properly.

i start facing this problem after i changed the belt 2 week a go, and yes the belt is tight

If It Is The Voltage Regulator. I Would Purchase A New Alternator, Instead Of Trying To Repair The One You Have. That Way You Have A Good Warranty

when you loosened the alternator by any chance did you remove or loosen any of the wires to it? if the belt is tight inspect your connections . If they are good id check my battery connections and fluid levles.. if they are good its time to remove both the alternator and battery and have both checked.

I agree with rusty, you may have knocked the harness going into the altenator. I would next check the battery post are they clean?
