Ok prelude experts i need some help,i have a 92 stype prelude with/the 2.2 f22a1,and its having charging system problems i replaced the old alt because it would not charge my battery,so i bought a new one.still having the same problem...i had the new alt tested its fine but when i take my positive terminal off it dies,all the wirings fine,the grounds good but the battery wont charge,but it will charge on my house charger and test out good.any other suggestions?its not the belt either so im lost the car starts and runs fine as long as my cars battery is pre charged at my house

 

How do the wires ends look? I had a problem with the wire at the alt., It was corroded and my battery wasn't chraging.
