After repairs still having problems Need Help

[milesz]

Last week I was on my way home (about a miles away) and I heard a sound, pop. The SAV (2001 X5 4.4) was hard the steer. When the car cooled off, I inspected what made that sound. The alternator belt broke and some of it wrapped around the fan cluch nut. The water pump was shot so I replaced the water pump, battery, thermostat, belts and upper and lower hoses.

The drive home must have drain the battery because when I tried to crank the car, after the repairs, there was no power. I charged the battery and went to the part store to buy a new battery. When I got there I was told I had a water leak and sure enough I did. The car is not showing any codes. After the battery replaced, I drove home and looked under the car and no water leaks. WHAT IS THAT ALL ABOUT? COULD MY ALTERNATOR GONE BAD WHEN THE BELT BROKE?
