I had an OEM alternator on my heap that had the stand apart voltage reg. i replaced the alt with a CS130 that is internally regulated. I looked up all the info on the WWW There is a ton out there. Basically you need a charge wire to your battery, a voltage sensing wire from the battery and a field exciter wire to the alt. There are some one wire alts out there, but I prefer the 3 wire as I personally think it just works better. Google is your friend

An internally regulated alternator will not need a voltage regulator. An externally regulated alternator will need the voltage regulator that is specific to it's model.

Here are a couple of examples of simple alternator wiring.

Make sure you've got a 12V system, and not a 6V. Both were common in the early 1960s.

If you have a 6V, you'll have to change more than just the generator - battery, ignition coil, and possibly a few other components as well. Still, it shouldn't be too bad.

I know this is an old thread but I want to do this conversion.
I'm looking at several kits:
1) Kaiser Willys Auto Supply: https://www.kaiserwillys.com/new-12-...illys-and-jeep
Not a 1 wire alternator. Looks like its a little more involved to install. Description of the parts you get seem vague to me.

2) Willys Jeep Parts: https://www.willysjeepparts.com/Alternators_15_02_B.htm
1 wire alternator. Seems complete. They do not answer the phone.

3) Vintage Jeeps: http://www.vintagejeepparts.com/prod...-and-Jeep.html
Only 60 Amps. I want 100 Amps.

4) eBay: http://www.ebay.com/itm/282277578593...%3AMEBIDX%3AIT
Looks like its the same as Vintage Jeeps but is 100 Amps. Also 1/2 the price of all the others.

Have any of you used any of these kits??

What issues did you have ?

Anything else I should know?

Thanks
Tony

You can get the bracket separately
http://store.alternatorparts.com/alt...onversion.aspx
Then round up the parts yourself. Most of the items can be had at the u pick yard for next to nothing.

You will need an alternator, ballast resistor, 12Vcoil, 12Vhead/marker/interior lights, and I recommend a conversion from the ammeter to a voltmeter.

You may also need a wider pulley for the alternator.

This is also a good time to install a fuse block. you can scavenge one out of a wreck or use a universal block(I recommend a marine application.

you will need a resistor for your fuel gauge. Aircooled VW stores sell fixed ceramic ones for cheap or you can use a universal voltage dropper

Don't forget to install a cigarette lighter/power port in or under the dash.

@JeepDaddy : Thanks for the reply.
My CJ is already 12V and I trying to move quickly.
I opted for the eBay kit because it was a good deal and it turns out this guy makes them for the parts sellers.
Went 100 Amp so no issue with battery drain while using the plow.
I was just looking for someone with firsthand knowledge of these kits, but apparently they are all basically the same.
Thanks

The CJ5 I'm looking at is still 6v, so I'm looking to do the same. Was told to stay away from the Chinese stuff.

@jimeyster : I agree about Chinese stuff.
The guy I bought the kit from is in Utah and only uses US parts and labor.
Go to his link in my posting above.
His number is there. Call him. Seems like a good guy.
I'll report back after I install the kit and let you know how it goes.

As mentioned before I ended up buying this:

4) eBay: http://www.ebay.com/itm/282277578593...%3AMEBIDX%3AIT

Went in really easily and works like a champ!
My lights are nice and bright.
