Car Alternator or Battery Issue

[^pomen_GTR^]

Bro, he has idle issues. Alternator not supplying enough during idle. Like I said earlier, if alternator consistently undercharging, the battery simply goes flat very soon

simply need to drive faster

Open road can lah, traffic jam how?.....hhahahhahahhahahaha

Next car think you challenge him for race.....hhahahhahahha

no need to rev2, use lower gear.

my wira cruising like 13.5V with aircon ON or OFF.
When idle, aircon compressor kick in it drop to 13.0V (rpm also drop) for short moment then regain 13.5V normal idle 900rpm.
May i ask , is it aircon compressor problem or "berat" ? Idle rpm take a dive to 600rpm momentarily.

A car at idle is not at it's most powerful rpm. So when compressor kicks in, it places an additional load to the resting engine. Hence rpm drops momentarily till ISC takes effect and raises the rpm to compensate

Yes, due to extra force required to turn the compressor, that is hwy need the FICD/IACV to increase the idling speed......

nothing wrong with the compressor lah ... ? jimat

Compressor Nothing wrong, just that since the compressor needs extra power to turn it, the engine idling drops before FICD compensate

Thats the nice way of putting it. The truth is that your engine is not powerful enough...hihihi

Hi All,

Since sweelt talked about A/C, just want to check, if alternator has not enough juice, will that affect the timing of A/C compressor kicked in? I found out that the A/C is slow to come in during slow traffic, where RPM constantly stays below 2k rpm. Once got on the free way and the A/C works just fine.

Thanks,
Ken

Not enough juice..
Worts if the compressor clutch is worn out as the compressor wont engage.
