It looks like these trucks came with a 117 amp or a 136 amp alternator. How can I tell the difference between the two when picking one from a junk yard?

 

download the service manual in the merry christmas thread and it gives you all of the part #s

you can also ask for a build sheet from Chrysler.

 

I can tell you that the stud on the back of the alternator where the wire attaches is larger in diameter on the 136a alternator. I upgraded alternators and had to change the end on the wire to one with a larger opening.

 

you also need to be aware that some years had a 6 rib pulley while others had a 7 rib.

 

If one had a 117 stock would upgrading to the 136 be worth it?

If one had a 136 stock what's a good one to upgrade to?

I'm pondering beings mine looks like crap buying a new one.

 

yes it would be worth upgrading.....if you have the 136 either you can get it rewound or there are some aftermarket ones i believe

 

I wish I knew where around me I could take it. I would do a deal like indy did and have them take it apart. I'd paint it then they could put it back together

 

For me the choice was easy. I needed a new one and the 136a was only $20 more.
