I have a very strange problem with my charging system on my 89 with a 350 and GM 2 wire alternator. I have replaced 4 alteryrnators in the past week, evetime trying another part in the system, battery,engine ground strap, charging wire to the battery,you get the idea. the alt will charge for ten min or so then quit charging. I have full battery voltage to the alt on both wires so i think that is not the problem. The starter seems to be disengaging when the key is in the run position.
im kinda lost on this thing. anyone ever run into this problem before?
