Picked up this 1960 Willys CJ-5 - lots of questions!

It's a voltage regulator but I suspect it's not functional. Depending on which alternator you have, it could have an internal regulator.

These Jeeps do not have a fuse box. They have a few inline fuses, and a circuit breaker on the light switch. Depending on what you want, you can buy a complete original style harness, or a simple hot rod harness. My preference is to fix what I have.

The old tech pages had a wiring diagram ... we had to move to a new server about a year ago, and much of the pages other than the forum were not restored. Maybe someone can point to a link.

Your steering pictures are a little myopic, but I don't see anything remarkable.

 

Here's how you get it home...



J/K. Seriously though, that's a nice Jeep--it would have cost you at least twice that around here... If you don't have access to a truck and trailer, you could just rent the smallest U-Haul and a car carrier (or get a truck from a car rental outfit). The adventure of driving it home would be fun if there's time to kill...including time for a breakdown. Oh, and get the Jeep CJ Rebuilders Guide by Moses Ludel...lots of step by step with pictures to guide you. Excellent book.

 

ok so I found out what I got in there:


but I cannot seem to find any information, the part number seems to not return anything. Maybe because it was made in Mexico, no idea. I don't think this is stock, does anyone know?

since I don't know what alt this is, I don't know what voltage regulator to get, so my next question is -- what do people typically replace the alt with if they go to a 1-wire set up?

 

Not sure why people are saying these Jeeps only get 9 mpg at 50 mph. My Jeep currently is all stock mechanically (FHead and 5.38's no OD) and it definitely gets in the teens at 50 mph. I am not sure exactly what it does get but it is close to 15 mpg.

My concern with any old CJ would be the steering. The stock setup it just to loose for fast speeds, even when it is rebuilt and working great. If it were my Jeep that is the first thing I would change and I would change it purist or not.

 

Overhaul the engine recently? A lot of people out there don't overhaul theirs with any regularity.

How'd you fix it to make it better? Saginaw?

 

That "longer rod that goes back to the steering box" is the drag-link, or as the manual will state, "steering connecting rod." It connects to the bell crank towards the front, and the steering gear arm back at the Ross box. The flap that's coming out is the dust boot. A drag-link repair kit is under $15 I think from Walcks 4WD. I just ordered one last week. Time to clean up the steering system!

 

Does anyone know if the later 70's and 80's alternators that came on the V6 and V8 engines would work?
like this: http://www.partsgeek.com/gbproducts...p+Alternator&gclid=CLz6j_v8kLYCFcR7Qgod3kcAgQ

or am I restricted to something like this (10SI)?

since the alt is already a GM unit and appears to be mounted fine, I don't think I'd have a problem using either of these...?

 

I don't know when the last time the engine was overhauled. In time more than 5 years for sure in miles probably would not be a lot.

Yes swap to a modern steering setup. It does not have to be Saginaw but that is the most popular and would be the easiest. My DJ frame came with the conversion done from the factory so I did not even have to contend with it.

 

Well, it might be the equivalent to some domestic alternator ... but the "Hecho en Mexico" label and "Neg. a tierra" does not hold out much hope.

Here's a page that identifys GM alternators - http://alternatorparts.com/gm_alternators.htm - if it's any domestic equivalent, it's a 10DN, but I doubt it is.

If I were you, I would get a any old Delco 10SI and hook it up 3-wire, not 1-wire. The 10SI was used in all GM cars 69-83 with ratings to 72A. The only difference other than the amp rating is the clocking, and they can easily be clocked to whatever direction you want.

I'd just go to the pick-and-pull and pick one from a car there. Yards in CA and AZ have lots of cars from this era, IME. These yards have a guarantee - if it does not work, you can bring it back and get another one. Your local Autozone will test it for you, if you have doubts.

Mad Electrical has some good tech about these -

They will sell you a wiring kit too, IIRC. http://www.madelectrical.com/catalog/alt-1.shtml - All you have to do is sort out the brackets and pulley.

 

Go 10SI. Jeep used those too - both of my J-trucks have original 10SIs.

The earlier alternators were Prestolite (V6 era - bad) and Motorola (early AMC era - ok but an oddball today and not as good as the Delcos).

You can pick upa 10SI at the pick-a-part for what, $15-$20? Something like that. A reman from the parts store should be about $40, with no core. Don't even consider anything else.
