Why would your Bonneville charge somedays and then not charge other days you replaced the alt and battery?
I have a 92 Pontiac and also had similar situation. Sometimes the voltmeter would go to 14volts and other times it would sit at 12volts. When I tested output from alternator to the battery with voltmeter, I did not get a good reading. Upon removal of the alternator to get it replaced, I noticed that the smaller (red) cable that goes from the alternator to the battery was loose in the connector itself. I cut the cable at the connector, stripped the cable some and crimped on a new connector. Reattached to alternator and put alternator back into vehicle. All has been fine since. Hope this may fix your problem.

sounds like you need to replace the battery. even new batterys sometimes are no good also an alternator tested when disconnected means it is tested with no load. this really means that the test was a waste of time

What cause an alternator to blow?
The usual cause of a blown alternator is overload. The alternator will also blow if the battery is connected backwards, even for an instant, such as during jumping. Sometimes, overload is caused by attempting to jump start another car while revving the engine of the first car. The alternator is not designed to carry the current of a starter. Depending on the alternator, protection might be built in, but don't count on it. Rev the engine only to help charge the other battery, and then let the engine idle while starting the other.
