And I don't have a volt meter I'll have to get one tomorrow to tell you, and it's been like this for a while now. But I do have a battery charger that has a alternator test on it to see if it's good or not I'll check that right now.
I know that you found the answer to your problem, but you might want to buy a good multimeter anyway when you get the chance.
It's a very handy tool to have, and they're inexpensive. I have an Actron digital multimeter that I picked up at the local Auto Zone for around $40. I cannot tell you how many times I've used the thing over the last 6 months.
