Alternator wiring diagram?

Ok alt was bad, as I said it had melted the metal around the connector. So alt is out and we are going to replace the entire wire, however I am in need of a diagram as to where this wire goes. It feeds into a larger bundle of wires and we lose the wire in the mess, so if we can get a diagram as to where it goes we can just bypass the wiring bundle and wire it directly to where it goes. And Docfixit - Thank you for all of your help, you have been absolutely wonderful!

It seem there is something wrong with a black inline box by the alternator. I need a wiring diagram where those wires run back to. For awhile when the voltage dropped I tapped on that black box and it would start charging again. But now that does not work. So either something happened in there or there is an open wire. Thanks

Was finally able to uncover enough of the wire past the burnt part to see that it was a black and grey wire, traced it around and found out it links to a green wire at the main fuse box, where the pos battery cable connects. Still planning on replacing the entire wire now just searching for a place to buy one. Again thank you for all of your help.

Roy not sure of what you mean by hitting?

We pulled a used wire (full wire with both ends) off an identical vehicle in a local junkyard, we ran it in with other wires and connected it correctly, the van is up and running. Thank you for all of your help.

On the little black box in the large 12 volt line right by the alternator. Do you know what i'm referring to Roy?

Do you really need a picture Roy?

1997 Caravan 3.3 285000 kms. Regular service including major service at regular intervals. Current problem is electrical system failure. The battery has been replaced and some faulty wiring connections were repaired on the fuse box. Now with the battery fully charged using a charger (12.7 V) the engine starts fine and with the engine running the voltage is at 11.8. Turn on the electrical appliances and the voltage drops to 11.4. Leave the battery without a charger overnight and the battery voltage doesn't drop. Failed alternator?

See the black thing in the middle of the picture with the red wire coming out. That is hat i'm talking about.

But do you know what is in there? I also checked to see if there is voltage to that point and there is not. So I need to know what is in there. There are no clips to open it up. It is twenty five years old and if I crack it open. I wont be able to replace it.

Although it is a junction box it does not open up Roy. There is no cap, there are no nuts as you describe. I'm talking about one thing you're talking about another.
