92 integra, low battery voltage level

**GSD** · 11-18-2008, 12:27 AM

i have a 92 integra, 2 door RS, and at night, in rain, or when its cold i need the defroster, wipers and heat turned on, but wen i run about 2 of these accesories at the same time, they both turn to low power and the car starts shaking slightly like the engine has a big load. the wipers struggle to go across the windsheild, the defroster turns to low, and im freezing to death, plus i have an audio system, 1000 watt sony amp and 1200 watt kenwood sub, and 0.5 farad cap., but even with system turned off i still get this problem, winter is coming and i NEED to do something about this fast, can anyone help?
thank you

Do you have any lights that illuminate on the dash when this problem occurs?

I think you should check your engine and battery ground cables. Make sure they are clean and tight at the connections and not melted, cut, or otherwise compromised on the length of the cable. The cables in question are: Battery to vehicle body, Engine to vehicle body.

Also you should check the positive cable from the battery to the alternator.

Other than that, it sounds to me like a faulty battery or alternator. I think an AutoZone or Advance Auto Parts can test your battery and alternator while it is on the car for free.

Good Luck.

i just recently noticed that when i accelerate the accesories, and everything gain power when i accelerate or the RPM goes above 1000. So im thinking it might be an alternator problem. is there a chance if i rebuild it or, should i buy a new one?
