More than likely it is simple corrosion, but heating the connector will cause it to corrode very quickly as well. Excessive heat burns the coating off.

 

[QUOTE=91crxSi,Nov 2 2010, 06:35 AM] yes, i have a new battery and alternator. the battery is fine. it has never been hot, no swelling, etc.

I will try the dielectric grease idea. thanks for that one...

about voltage fluctuating, i tested two cars (another s2k and an altima), while idling, and there was no fluctuation at all. I tried turning on headlights, and the radio, and they showed no fluctuation, while my car would drop voltage when I turned on the radio and headlights, but never getting as low as the two control cars.

I was

 

ok. so the original alternator was definitely overcharging, with busted diodes. the first battery ended up bloating, and smoking, and did not explode, fortunately. So, i assume that the power wire to the alternator was overheated due to this, and the coating is now gone, which lead to the corrosion.

what should I coat the wire with?

i will definitely clean my grounds and add additional ones. i do not have a sound system. the car is MY01, so im sure it needs cleaning, and additional grounds should be nothing but beneficial.

THANKS ALOT GUYS!
