Replaced engines to a '96 from a '97. battery light came on. Checked battery and alt. even swapped alternators and same thing. then i swaped wire harness's with one I know is good, same outcome. checked and rechecked every connecton in engine compartment. problem is, I bought the '96 with a blown engine so I didnt get a chance to see if everything worked. The passenger window does not, might this be an issue. The battery has a draw coming from it somewhere. It does quit when I unplug the battery. It also quits running around five minutes after it starts. If anyone can help i'd be greatful..
