Need alternator wiring diagram for 2012 honda odyssey. Does anyone have one? I have changed the alternator out twice in a year...most recent 2 months ago. I do not think the wires are correct since I had to replace the pigtail. It was still saying check charging system but ran for a good 2 months before leaving me on the interstate.

 

Have you verified the battery terminals are in good condition. You can also check continuity from the pigtail down to the other end. When i had charging system issues, it was nkt tbe alternator, battery, pigtail, or harness. Came down to be the battery terminal was loosing its hold on the cable. Not on the post, on the cable itself
