The car is shutting off because it had ben running off the battery until there is not enough juice left in the battery. So ya, gonna have to check the wire that runs to the battery from the alternator & the small wire that plugs into the alternator. Lot of times that plugin will go bad.

That plugs into the alternator. That plugin can go bad, they make a replacement.

What is that wire for?

It runs power to the voltage regulator. Turns on the alternator so to speak.

Is the alternator working, or is something draining the battery with the key off? You changed you terminology.

Ok thats because the alternator is still not charging and the car is just running off of the battery juice. So, you know the alternator works. It has to be in the wiring some where. I know on my vehicle there is a fuse for the air bag, and for the gauges. If one of these are not in place, my vehicle will not charge. Otherwise without being there to see, I don't know. But I will be thinking of anything all day for you.

Well I dontbknow if this will help but the battery light by the gauges is on and the check engine light will come on and off. But thanks for helping me

I had the same problem after 3 alternators,testing every wire even the fuse. When I replaced the 20 amp fuse I found that it wasn'tmaking a connection,so I bent the tabs closer and my charging system started working.
