Have you got a multimeter?

Switch the meter to test DC voltage and test the voltage across the battery terminals with the ignition off. Record the result, should be a bit over 12v.

Now start the car and test the votage across the battery terminals again. It should be more than the first test or it isn't charging. You might want to get a mate to rev the engine a bit.

If the dynamo is goosed the car will run fine until the battery goes flat

 

Edit, don't forget to check for loose wires and corroded terminals etc it might not be the dynamo at fault.
