Can a bad/failing battery cause an alternator not to keep up?

[QUOTE="Sephious, post: 7377662, member: 632635"] I'm not sure what size the alt is. I just know that it's supposed to put out 200 amps at 1200RPM. It's the same size as the stock one, but seems heavier. The sub amp I'm using isn't even close to being maxed. It's only using about 900 watts, if not even a little less than that, so I'm nowhere near 150-170 amps. I'd be closer to that with everything running, including AC and brights. Even then that number is probably a little high. I've clamped my alternator wires and they seem to push no more than about 5 amps together, which seems a little odd to me. EDIT: DEERRP. I have an AC clamp. I can't measure DC current, so I can't tell how many amps my alternator is actually pushing. [/QUOTE]
