See this post, but I think it will stick better if you read from the top post.

Begin with a charged battery and make sure there isn't any high charging or discharging of the battery.
Monitor the ammeter when the car is running.
Someone here in recent memory fired up a new engine with a battery that needed charging.
The alternator worked great, so provided over 40 amps during the break-in. The owner saw the high charging on the ammeter but didn't understand the importance. After 20 minutes all the connections were melted. :(
