Help Wiring Alternator Needed

Thx in advance

Have a 62 CJ5. Am putting a replacement 134 in. It has come with a Motorola A12NW526. My CJ has three wires coming from voltage alternator - red, blue and green. Can I get some guidance on how to hook these wires up to alternator.
I assume that the red wire may go to the top red terminal. The bottom nut(s) appear Lyon be ground. Which wire is ground - blue or green? That leaves the other one?? The alternator has an electrical tab coming/sticking out. Wondering how that figures in?
Many thanks. We are getting close but there are just enough differences between this 134 and the takeout to make it challenging. I will be posting another dilemma with oil line hookups.

 

Pictures would help but it sounds like you are trying to use the wires from the voltage regulator on the firewall to connect to the alternator.

 

Even up to '71? Surprised that customers would put up with it.

I would expect that a '62 would have come with a dynamo generator. Suggest to the OP that he could be wrong in terminology or the alternator has been swapped in. Suggest you understand the difference between voltage regulator, alternator and generator. There is no such thing as a "voltage alternator." The number you give probably has no meaning to us. If swapped, also suggest he copy the wiring from a later Jeep with a V6 and alternator from the factory.

 

Yes, sorry I certainly didn’t mean “voltage alternator”. I just leaned how to upload photo of alternator and three wires coming from regulator. Will get pic of it soon. Thanks for continued help.

 

Actually, I found a A12NW525, but no AW12NW526. Could be specific to the 134, which I have no book for. The AW12NW525 is Jeep PN 937482, and it was available in the early 60s, though '62 seems quite early for an alternator. It is indeed a Motorola alternator. This unit would have used a voltage regulator mounted on the firewall or fender, and there would be wires from the Jeep to the regulator and alternator, and wires between the regulator and alternator. Should be easy to copy the diagram from a later V6 Jeep that is certain to come with an alternator.

 

Ok, so I understand you to say the OEM voltage regulator on the fire wall will not work with the Motorola because it was designed to go with original generator with the 134 I took out. Unfortunately that generator is in AZ because the “new” 134 came with a rather good looking Motorola alternator.
So now what I do? How do I hook up the alternator? Any help, thanks in advance.

 

Might you have a part number for that Motorola regulator? I tried to enlarge pic to get number but couldn’t quite read it. Or even one for sale?

 

Back in the day, the Motorola alternators popped diodes quite often. I suspect it is these failures of the old alternators that continue to today. It is possible that improvements in semiconductor quality and durability since then have made them more durable, but then you are dependent on the rebuilder to upgrade the parts quality.

If you really want the Motorola regulator, I suggest you look at an early Wagoneer, like a '65 or '66, for a matching regulator. The number I came up with was from that era of Jeep. Like here - RockAuto

You must connect this up correctly though - Suggest you look at a Wagoneer wiring diagram from these years and follow that.

 

X10...I learned a lot from this site on how to change from an older externally regulated alt to a 10si. Much more simple wiring. Pulled all wiring and re-wired everything. Much cleaner and works well.

 

was used up to 71 in DJ's 4cy, J1000 6cy, J1000 8cyl, Jeepsters 4cy and others.

 

Remember if you go with the Delco 10SI alt you need a wide groove pulley to match crank pulley belt width.

 

Thx to both of you. I now think, having heard all this, the plan is to get the CJ going w/o alternator or generator. I am trailering it down to AZ first of January. That’s where we took out the shot 134 last winter. I have the original generator in the shop there but will keep the great info on the 10si. Thanks. Truly appreciAte this forum

 

When I still ran my flathead 134 I used a older common ford truck regulator on my Motorola. I still have motor in garage if interested in using one I can take pictures of how it is hooked up you need to cut one wire of regulator if I remember. Ran that combo for 10 plus year with no trouble.
