Ok i know its late but heres whats up. I helped my girl install her CAI today. WHen i was taking out the battery i noticed alot of the white corrosion powder on the terminals. I cleaned out some of it when i was putting it back on. SHe called me about 5 minutes ago saying that it wont start and has no power at all.... she turns the key and nothing no lights etc. I asked her if both battery terminals were one she "said" yes. COuld the corrosion be causing this or what should i look for. Thanks!

 

Maybe you drain the battery, swap them or check for lights or turn your system on, if that works, make sure the terminals are there nice and tight, other than that i dont know what to tell you.

 

If there's a lot of corrosion yes it could be the problem!!
Clean them(battery pole) with sand paper to get rid of all corrosion!!

 

or you could mix some water with backinf soda and that will take it right off...but make sure that the terminals are tight... i had this happen to me except it started and i drove to the gas station then it wouldn't start so i moved and tighted the terminals and all was goog

 

There is this little tool that cleans them. They have them at AutoZone for like $4-5.

 

You can use a soft drink to clean them off. Then rinse with water.

Autozone has little disks (green and red) for $0.99 that keep the corrosion off.
