So other day start my truck light comes on says battery not charging. Then soon went off. So I connected torque app to keep eye on voltage. While truck is on and it is charging at the obd2 it's reading 13.5-13.8. Later while driving I hit gas to pass it down shifted and bam voltage drops to 10.6-11.3. Then my hids flicker because that's what they do when truck is off. That lasted a minute then jumped back to 13.6. Then normal cruising 65 on highway does it again. This time light for battery not charging comes again.
I want to jump and say bad alternator but I assume once alternator is bad it's just bad won't charge at all.
Another thing to add related or not I dunno but couple times I heard that shop vaccuum noise I usually hear at start up (not all the time). But was while I was driving and only for brief two or three seconds
Any help before I buy an alternator would be great thanks guys
