All,

So I get a call from my oldest this morning on his way to work.

Seems the car has just plain died and he's sitting on the side of the road. As we're talking over the phone, he notices that the D + connection off of the alternator is not attached. He attaches it, but no joy, the car still won't start.

I show up, and check the voltage at the battery. I've got 11.5 Vdc. We jump the car and it starts. I check the battery again, I've got 13 Vdc. Not good at all, but its charging.

I follow him home and as of now the battery is being charged while it sits there. I'll have to check when I get home as to when I bought the battery last, but I have a couple questions first.

1. Other than the D + connection telling me whether or not the battery is charging, does it do anything else,

2. How concerned should I be about 13 Vdc at the battery? I know I need to check at the alternator, and am kicking myself now for not checking it, but we were both in a hurry. I'll check tonight and report back.

Thoughts???

Thanks,

Matt
