I've found few helpful suggestions online, some far from logical. I'm hoping you guys can provide me with a bit of your wisdom. I have a decent degree of knowledge / experience in automotive maintenance & repair. The confined work space of this job is driving me towards a padded room! Any help would be greatly appreciated.
Thanks!

We have replaced the alternator four going on five times now in which three occurred in the last two months. I have replaced the crank shaft sensor an wiring to the sensor. I have a good fully charged battery but drive the car for awhile maybe hour an battery light is on. When the second alternator went out i thought it was strange had it two years. Then kept having same problem bad alternator changed it same problem voltage regulator out changed it it would not start. Checked crank shaft sensor it was bad replaced it plus the wiring to it since had bare wires. Checked battery its good. So car runs okay for an hour or so light comes back on soon battery dead. Charge it test battery an alternator an voltage regulator out. An I had that alternator tested before we installed it. Tested fine. Any suggestions as to what could be causing the battery to not charge? Also, when it does run it runs really rough. I have checked the fuses and relays an no issues there so far. No corrosion on battery. Plug on alternator is connected an good. But battery is not charging at all.

Hello,

Lets check the fuse # 18 in the under hood fuse panel. Here is a guide to help test for power and the alternator wiring diagrams so you can see how the system works and the fuse location as well. To make sure the alternator is installed correctly here are the guides for that as well.

Check out the diagrams (Below). Please let us know what happens.
