Battery Not Charging

[woode12]

On my 1989 325 I put in a new alternator and battery. The car will run for a wile then die. When I test the system I only getting 12.4 volts. I cleaned all the wires. The light on the dash comes on when you start the car then will go off. When I drive I can drive for about 30 min. then the car will die. Why an I only getting 12.4 volts out put from the alternator?

maybe you got a bunk alt. it happens, was it a remanufactured alt or brand new? what brand?

New on. It hooked up right. What volts is it sopost to be?

13.5 volts on a fully charged battery and 14.25 on a battery getting maximum charging possible.

The issue is the alternator or the way it is connected.
