possible dying batt or serious problem?

Ok so I finally changed my corroded alt wire and its been about a month now and now I'm having a weird problem.
Truck starts up fine runs good, but this is what I first noticed.

1. Parked at work and turned off my rig only one click, I keep my radio on while I put my shoes on. Everything shut off radio dash lights everything.

2. Started up truck after driving it 15mins it stumbled and batt light came on a brief second but went away and idled smooth.

3. Just now I rolled down my back window to grab my mutimeter to test the batt window rolled down fine but didn't go back up. Power locks didn't work pooped Hood 11.97v to the battery. Stuck the key in the ignition turned to on and nothing, stepped out of the truck to check my multimeter and boom it clicked on radio was on everything worked. Started truck 12.23v at batt while running 14.v at the alternator. I can repeat the problem by turning the truck off and leaving the headlights on and rolling the windows up/down and try to start it and nothing...leave the key in the on position for a bit and it'll click over and turn all my accessories back on

Start by cleaning and tightening all the battery cable connections, +12V and grounds.

You have a wiring or alternator issue. You should have 14 volts at your battery while the vehicle is running.

If I put the neg side of my multimeter to my neg on battery and the positive side on the alternator bolt I have 14v when its running...then while its still running I put the positive side back on the battery it reading 12v

Got to be a issue with new wire if it all worked right before.

Will do...hopefully it's something as simple as this

It was working well for about a month with the new wire..until just recently

A bad connection can cause this.
Check wire from alt out to terminal block, and terminal to batt positive.
Then there are 3 ground wires, batt to body, body to engine block, body to frame.

Thanks fourwd1..cleaned my positive side terminal and took the dremel to my positive leads to get a better connection to the battery and that did the trick...she's running good again
