Battery or alternator bad?
I've been having some weird problems with my 02 4dr 4x4 and I'm thinking it's either a battery or alternator issue but I'm not real sure. Here is what is going on.
I noticed a few days ago that with my lights on my PRND321 and the odometer were flickering some. I have videos below. Then the next day it wouldn't start like the battery was dead so I popped the hood and move the battery cables around some and it started up but cranked for a bit. After I drove it for a bit it was fine.
Then the next day I started it and noticed the dash lights were dim and my volt guage was a little under the 14 mark and when I revved it up the lights would get brighter. After about 5mins of driving everything was fine.
Then today I start it up and noticed that some of the dash lights didn't come on. Right after I take off the tach, speedo start jumping and the lights on my dash would come on just like I had turned the key on all while i'm driving. After about a half a mile it stopped and was fine all the way to work. Any ideas on this would be great, I have videos below of the first flickering incase that helps.

When the key in the off position the battery voltage should be around 12.6 Volts. Once the engine is started the battery voltage should increase to 13.0 - 14.5 Volts as a result of the alternator charging the battery. If it does not, the alternator and/ or the voltage regulator are most likely the cause of the malfunction.
