Default Alternator, Regulator, or Both ?

My 2007 Regular Cab 2.3L 5spd Manual Ranger is having major electrical issues.......
I deliver for Domino's with it, and it started dying between delivery runs. I'd have to bump start it before each run. I thought I had killed the battery by leaving my overhead sign plugged into the cig lighter all shift long. I took it to Auto Zone and they tested the battery without the truck running and told me that the battery was shot, had very low gravity.
I replaced the battery and it started and ran great for a day, then stalled out on a run.....lights dimmed, sputtered, choked, died. I messed with it a little and discovered that it would start and run without any accessories on......the more I turned on, the more it choked, sputtered, and missed. Anytime I turned the headlights on it would die immediately.
Next day I installed a "new" alternator and it ran like a champ for 2 days before dying again, with the same symptoms. This time though, the turn signals are freezing on, the left signal is flashing very fast, then flashing normally, both headlights and park lights glow very dim with the light switch off and the key on, it seems as though the electrical system has lost it's mind.
I'm wondering if this could be an intermitent voltage regulator problem, or if I just got a bad rebuilt alternator. I have never seen a vehicle wig out so badly with a bad alternator though.........
Also, I read something on here about charging the battery when installing a "new" alternator......battery was new, would that make a difference ?
Any suggestions that might get me back on the road again will be greatly appreciated.........
