Question

THANK YOU!

Answer
Hi
I would check the battery, and I also would check the Alt again.
Depending on what or where all this was done, it should be under some sort of warranty.
I would take vehicle back to shop that preformed work and have it checked again. If same parts replaced before are needed, it SHOULD be under warranty (Look at your recipt to make sure)
I would also have all the battery terminals cleaned and checked. Replace and terminal ends that are corroded heavily or that will not tighten properly.
I Hope this helps
Just advicce from experience.
Good Luck
