My brother in law said his car is having problems starting. I checked the battery voltage, 10.6V. I had him start it up - it was a weak start, but it did start, and after it was running I read 14.6V. So I told him that his alternator is good, but his battery is shot, probably a shorted cell, and that he should replace it ASAP, as the alternator could fail as a result of trying to charge the bad battery.
I was pretty confident in that answer but the more I think about it, the more I have doubt that there might be another problem. Automotive electrical is my Achilles' heel. Just looking for a sanity check here.
