[QUOTE="NFrazier, post: 7791665, member: 571239"] .....You're right, that's what I said. The battery acts as a load on the charging system. If there is a drastic spike and the voltage regulator doesn't react quick enough, what's picking up the slack? The battery. You neglect to actually read things, or you simply ignore words. I did not say the alternator didn't produce ANY current, I said MEANINGFUL current. As in the 100A alternator is not going to be able to produce 100A at 800 engine RPM. The alternator still has the ability to supply current at idle, but it's not going to supply all of the current required to run all accessories in the vehicle, and any additional that the car wasn't designed for.
