Alternator Issue ?????

[mikalkouki]

Ok... so i ditched this thread zer...ymore

because I found that my alternator has successfully killed my factory and my yellow top optima twice... put it on a tester and as soon as you cut the charging the voltage drops .10v a second until it dies and the car cuts off..... installed another alternator today and it still does the same thing

I have the ka chassis harness hooked to the positive terminal the screw on the back is grounded to the block and the brown plug is not damaged. I also checked the alternator fuse for continuity and its ok.... Anyone ???
