Car won't start. Help!

[COOTER]

One week ago, the Model A started and drove fine. Today, it turned over very slowly but started. The ammeter is showing zero charge. If I turn the lights on, it's showing about -10....so, I assume it's working.

I drove it around the block, wishfully thinking that all would be fine. As soon as I got back home and came to a stop, the engine died. Now, the starter won't turn.

The battery is showing over 6+ volts and terminals are tight.

Troubleshooting is not my strongpoint.
