Current voltage problem...

[merz2]

Im driving Honda Accord SV4 with H22A engine...my problems here when i turned on headlight and aircond, and then when the aircond compressor kicked...my car voltage drop to 11 something and sometimes below 11 at idle....its happened when i turned on both aircond and headlights only....if i turned on one of them its not happen....when the car moved its ok voltage 13++...sometimes when i did emergency brake with both a/c and headlights on, the car died cos voltage rapidly drop too low....seem like alternator cant recharge at time...my car have abs braking system....i already change alternator to 80amp....oem one only 65amp...but its still happened...any solution to fix my prob....???

is the newly installed alternator a new unit sir? if its a used unit, it may not be supplying as what rated for it

yes its new installed alternator(new unit)....voltage stabilizer oso done...branded one sun hot inazma....just happened when both on...if a/c only on...its ok...same if headlight only on its normal...alternator amp not enough ka?....or must upgrade to higher one, lets say 100++ amp...or maybe its bcoz of my alternator belt...alternator belt quite old oledi....from halfcut i think....any potential alternator belt can slip due to wear an tear..??

no sir, i think the problem is relay related. please check the relay for both system before changing things unnecessarily, and report back.

change old beltings for dat peace of mind sir, tighten as per manual (cewahh, bahasa katerbang ni, hahaha..), not too tight or else it wont have tolerance between cold and hot condition.
