Replaced the alternator in my 2.0L: 2 weeks later, battery light flashing.
Manual indicates a loose connection to alternator, so I tighten them all up.
Notice the alternator output connector (The big one on the red insulated post) is a bit loose and well corroded, and now quite a bit scorched near where the wires screw on.
Try to tighten that connection but battery is still not charging.

Question: could the loose/corroded connection itself cause the scorching? Or do I need to track down another electrical glitch somewhere?

BTW, it is not surprising that it was corroded, because I had to use the connecting post from the old alternator (the new one was shaped differently and didn't line up right to connect with the output wire).

Thanks for any input.
