Do a static current draw test. (see jpeg).

Go to a shop and get a load test on your alternator.

The battery's only function is to start the car.

Replacing that current drain and running the accessories is done by the alternator.

Once you have started the car, you could (if there was some way of preserving the diodes by some type of load), drive on the alternator.

However without a load, the voltage would ramp up on the diodes, and smoke them all.

Good luck,
