When the alt ground fails, you'll get no charging and no alt indicator light. The lights might dim a bit as they start running off the battery at ~12V instead of the alt at ~14V. In my case (different car), the wire had corroded away from the push lug. Not even 65+ MPH saved the day.

Wedding days can be so much fun.
