Bladecutter,

You are wise. A thread came up a couple of months ago and I tried to explain about the bucket (battery), pump (alternator) and the water (electrical power). And was basically told I was out of my mind. Everyone seams to think the battery is only used for starting the car and after that the alternator takes over.

I've always been taught that electrical power comes from the battery, the alternator supplies power to keep the battery fully charged. During high power demands (fuel pump, ECU, lights on, top coming down, radio on, heated seats on, etc) is why the battery is so big, it needs all that capacity to keep up with the demand.
