Alternator wiring question, 83 Eagle

[Zoro]

Helping a buddy make sense of an '83 Eagle. Wiring harness has been gutted for the most part. It has the Delco alternator with the 2 pin clip on the side and the single stud out the back. We're trying to set this car up as simple as possible and just need it to charge the battery.

What can we do for wiring? Big red stud on the rear straight to the battery terminal of the starter solenoid. What about the 2 pin clip? Where should those wires go to?

Thanks!

The #1 post goes to 12v+ from the ignition switch. Post #2 gets a jumper to the battery post on the back of the alternator.

If it doesn't go directly from the main terminal to the battery (ie: shortest route) then run #2 to the battery + or the battery will undercharge. Been there, drove me crazy till I read GM's explanation and why battery post corrosion does the same thing.

IIRC on a normal wiring harness there should be one red and one green wire, correct? If those colors are correct then #2 is red and #1 green? I guess I could always go and look at my Eagle lol.

Probably gonna run it like Eaglefreak suggested.

You stated you just want the battery to charge. If you hook up the way I sated, the alternator light will probably be on in the dash if you don't use the original wire, since I believe the 12v+ goes through the ammeter and then to the #1 post.

Terminal 1 is usually blue or green and goes through the alt light in the dash (full 12 volts can damage the regulator long term and it's feedback can run the ignition system so you need at least a diode to make it shut down, but 10 ohm resistor bypassed around the dash light is factory setup)

The other option is buy a GM 1 wire alt. Straight to the battery + and a good ground cable from the battery - to the motor and body, it charges whenever the motor is spun up to high idle.

That's the plan. This one is a junkyard rescue turned woods beater. Not an ideal life for an Eagle but much better then the metal muncher.
