well ive search the forum and i cant seem to find anything but ive been having issues with my charging system.anyways at night thats when it really gets bad.if i have my a/c,stereo,lights(hids) on when i come to a stop and i have my brake lights on the stereo turns off but comes back on and also my driver light starts to flicker once im going on the road already its fine i just bought a battery this morning and i havent notice any change could it possibly be my alternator? if you have any tips it would really help.

thank you

 

Why not perform a check of the voltage... Make sure you're running somewhere around the 14V area. Any lower and it might be catastrophic for the battery and you.

 

ok well could it be that im running alot of things at once? im actually going to put a s5 alternator tonight and see how that goes.

 

It could be, but it shouldn't be. Check your voltage at 2500 RPMS, with the radio, lights, and heater on full blast. You should get at least 14 volts across the two posts of the battery. Perform this test, then worry alternators or whatever else may be wrong...

 

its probably the HID's check if when you turn them on the alternator starts humming. this happened to a friend of mine and he had to get a higher amps alternator.

 

True HID lights with a transformer will draw less power than a Halogen or Xenon bulb will.

Typical Halogen = 55 watts
Typical Xenon (pretend HID) 90 watts
Typical True HID system = 35 watts

 

Maybe those were the ones my friend bought. thanks for the info

 

is the idle bad...? at all...
