2007 escape xlt v6 30. P0622 code. swapped 3 new alternators in 2 days just to make sure its not that, was really fun. Ran new wire from pcm to alternator clip(brwn-white). Battery is new. Still getting p0622 code with battery light. 14.7-8v with alternator clip plugged in. 13.6 unplugged. Im out of direction on what to do. PCM bad?
