Its time to start wiring things up. I've looked around and found quite a few wiring diagrams for stock 6v but none really for a 12V alternator set up. This is the diagram from cj-2a.com. I've changed it to my understanding but I'm sure there are some holes in it. Let me know what you think.
 
Here's my alterations:

That's the general idea, just replace the generator and VR wiring with the 1 wire from the alt. On mine I put a dummy VR on the fender, then ran wires from the Alt (one real and 2 dummies) to the VR and then used a maxi fuse inside the VR housing and wired it to the ammeter, this was all for appearance.

Hi
Here is what I will be doing. 1 wire alternator, 12V.  The thread is in jeep projects, "Curlew Flat Fender re-wire"
Still have not added the fuses into the diagram

captain... yours is wrong.  You have no way to start your engine with a switch to the solinoid.  Unless I am looking at it wrong.

Yea, the thin orange wire to the solenoid should lead to your switch.

Beautiful! Thank you guys so much! That is exactly what I needed.

Warbrds: Couple questions on your diagram. Does it matter which terminals you connect stuff to
(+ or -) on the ammeter. There is a positive and negative on the meter. Also on your alternator, you only have one wire going to it, is the one in the diagram the one to the BAT terminal or sensing #2?
On your solenoid I take it that the two thicker lines are the two larger posts on either side? Thanks again!

I went to my local auto electric shop with whom I have dealt with many times. I bought a 1 wire Delco alternator from him. The BAT wire goes through the Amp gauge to the Pos terminal on the battery.  You do not use the Field or Sense wires.  I also had him set it up so produce current at low RPM, this is important as a lot of alternators have a coming in speed above 1500 to 2000 RPM. Mine will be producing juice as soon as it is turning. Takes a little rewiring inside, which the auto electric shop did for me.
 
Yup my solenoid is set up that way.
 
Without looking at the Amp gauge I believe it is BAT wire to + and then on through to the positive terminal on the battery.
 
You can run the BAT wire directly to the battery if desired, just will not have a charging indication from a gauge. I like having the guage
 
Hope this helps some

Captain,

If you want to use relays (which I highly recommend) to carry the load for headlamps and other high-amp drawing circuits, take a look at my diagrams here: http://www.thecj2apage.com/forums/topic11156_post163198.html#163198 - scroll down, they're at the bottom of the page.

I've got the same 12V Delco alternator that you've got.

Captain, your first diagram on the thread is exactly what I built and it works fine but I do not have a clue how to continue as I will need to build in the turn signals in the system, have you got a good wiring system for that as well?

No I don't. Here in Utah if it didn't come with the vehicle originally it is not required (seat belts, wipers, washers, turn signals) Thats just one thing I don't have to worry about Smile, but you are required to do hand signals. Walcks sells a turn signal kit that straps to the steering column for about $37. I'm sure it comes with instructions. I'd find out who has installed one here before and find out what you need. Hope that helps.

Sten,
I put on an aftermarket turn signal that clamps on the column. It does not interface with the brake lights as some do, so I added extra rear lights and used 2 relays to allow the front parking lamps to work as both park and turn signals. I have the circuit diagram somewhere if you want it. I found it here on the forum so you could try a search.

Thanks, this helps me, will ask Walcks for the kit.
