    There is no reset, if the problem is fixed the light will cancel, so you have not fixed the problem

The light only comes on for 3 reasons. 1 the regulator is bad and is not charging the battery. 2 the altenator is bad and is not charging the battery. 3 there is a fault in the ecm that is keeping the light on. if the battery is being kept charged up then the problem is in the ecm. You might be able to fix this by disconnecting the battery for 30 minutes. Resets the ecm. There isn't a reset for the light.

Can alternator put out 14.2 volts but not enough amps to charge battery and turn off dattery light?

Yes and no.
It sounds like you have a wiring problem.
The alternator output could be 14 volts and only one or two amps, but that would be enough to kill the warning light. Its more likely the alternator is charging but the current is not reaching the battery.

I replaced the battery on a 2005 chevy impala. how do i clear the "service battery charging system" text and red battery light on the dash?

That sounds like not the battery. It possibly the alternator.
-Use a volt meter to test when it's running. If it's below 13 volts
the alternator is bad.

Intermittent Charging Problem. I posted a question a couple of days ago about an intermittent charging problem. The volt meter will drop down to 12 volts +- and the battery light will come on and remain...

When you wire it in, run a hot wire directly from the battery to the volt meter (this will give you a more accurate reading) The instructions will come with the volt meter on how to wire it. Just make sure about the hot wire coming directly from the battery.

What I would do first is take off the alternator and go to a parts store and have them test it for free. This will save any additional purchases. Good Luck.

1000 volt jump start placed incorrectly

Your system probably has a lot of relays and other electronics that are bad now. Your Electronic Control Unit (ECU) may be cooked as well. You may also have a fusable link that has been blown as well. The fusable link is basicly an in-line fuse that you have to replace the wire to replace the fuse. Get a wiring schematic and look to see if theres a fuse or similar that you misssed. You may find that you dont have power going to all or part of one of your fuse panels.

Hope this helps...

Occasionally Battery light goes on momentarily

could be a defective alternator, but the mechanic will need to check it while the light is on. I know that sound like BS but if he checks it while the light is off, of course its going to check good.
