A generator in good shape will provide all the current you need. The problem I have with the stock generator is the need to adjust the current with the third brush. In the past on other cars I have installed a voltage regulator (6 volt type) in a hidden location and used that to control the field windings. That eliminates the need to adjust the third brush for the seasons and the type of driving and eliminates over charging or under charging the battery. The generator with the regulator keeps up with the loads.
Do you have the manufacturer and model number of the 6 volt regulator? Did you use it on a Model A?
