Take take your volt meter and connect it across the battery, take a reading.

Start engine and set to a fast idle and take another reading.

Let us know the results and we can go from there.

What the the vehicles ammeter show ?

The only reason I'm suggesting taking the readings directly from the battery is due to the possibility of poor/dirty connections.
