Not sure how to wire in…

[Bigboy1063]

My 67 Dart GT was parked for years and at some point, someone helped themselves to my alternator. They cut all the wires, so I’m kinda clueless as to how to wire it up properly. I’m an R&R guy and really don’t know much about electrical stuff. Any help would be greatly appreciated… thanks in advance! See the attached photo please. )I’m sure it’s not too hard, but I just don’t know what goes where)

Start here....Wiring – MyMopar
Download or print the wiring diagram, you should have one for reference regardless.

There shouldn't be many wires running to the alternator. The heavy wire will go to the stud. You could have 2 wires (if converted to electronic ignition and a 2 field alternator) that run as field wires. One may be a green wire coming from the electronic voltage regulator and one may be blue wire with a white tracer coming from the ballast resistor. I say "may" because someone may have run different colored wires during a conversion or previous repair.

If you have the pre-electronic (single field) alternator, you will only have one field wire that may be green in color and will be coming from the field side of the voltage regulator.

The Dark Green wire should go to the field terminal, it needs a female spade style connector...

The thick black wire (Probably a 12 Ga) goes to the post with the nut on it...

According to the schematic you may have second wire going to the stud that also goes to the horn relay..

Being a 67 it should have a single field connection, the other side should be internally grounded, but often these days parts houses supply a later design alternator with two field connections, if that is what you received you need to ground the second terminal...

Thank you very much! That actually makes sense to me now. The “Black wire w/white stripe” just seems small to belong to the battery post on the alternator. One of my searches suggested a 6awg from that post directly to the positive post on the battery? Again, the their that stole my alternator, helped himself to the wiring too . So, that smaller “Black wire w/the white stripe” will handle the charging requirements…. Thanks again for the help. Getting closer now to be able to move it around, running now, new tires, put it in gear for the first time in 47 years and shifted into drive/reverse w/o an issue!

Run over to MyMopar and download the factory service manual. Someone above also suggested the aftermarket diagrams, but a caveat. Those can be easier to follow but are not exact as the factory ones

Also, on that car, the horn robs power off the alternator stud. The horn relay was mounted right there close by on the fender apron or rad support. The remains of that harness may have part of the horn wiring. A small black is the horn button wire, going to the relay.

These cars can have a lot of trouble with damage in the bulkhead connector. The big red and big black are the ammeter circuit and are particularly prone to damage. The IGN "run", dark blue, comes from the key, is hot in "run" and feeds the ignition system and VR. It is NOT fused, and those can be trouble as well.

you might want to carefully separate the bulkhead connector sections and pull them apart, inspect the spade connectors in there for damage, from heat and corrosion. The wiring was never large enough for very large alternators, and THAT is the reason guys use a bypass wire from the batt to the alternator. You NEED to fuse or breaker protect it, however, and the bulkhead connector still needs to be in good shape, and the black and red still act as power feeds into the pass compartment, even after the bypass.

There's more but I don't want to get really complicated

On the firewall, black box is voltage regulator. Blue wire @ one end,, green wire @ the other. That's the green going to the alt' field terminal.

Thank you for responding, that’s very helpful information, thanks again!’
