It has been running good. Vehicle wouldn't start today. I had to jump battery. I have put in new alternator (it is good), new battery (checked it is good), new radiator, new fuel pump, new power steering pump. I know I need a new serpentine belt. Could that disrupt alternator from charging battery? I need ideas. Thanks.

Hello, I'm Danny.

Yes, that is a possibility. If you say that the battery and alternator have tested good it is possible that the serpentine belt and or the tension-er are not holding the belt in place with proper force/tension.That will cause the problem.This will keep the engine while running from having the alternator keep the battery charging. Here are a few tutorials to view showing what is involved:

I changed the serpentine belt and still had the problem. I started checking the wire connections and located the problem with alternator wire in clamp was loose and secured it in. Starts everytime now and battery stays charged. Thank you
