I rebuilt mine with better parts to output a bit more power, along with an additional 8 gauge wire back the the distribution terminal and adding all the LEDs.. it all helps
Thanks for the reminder. Definitely Want to add the extra cable.

I was looking into alternator parts today. The early housing info helps a lot.

Thanks!
Thats the place I was looking at today. Good to have a recommendation.

Nice, too, that I can build a dual rectifier, 350 amp version of the alternator!

Yeah the dual rectifier might not fit. Also you limitation for power is the rotor

I bought a rotor I have a stator out of a 140 amp late model. I bought the heavy duty rectifier DR5176PF and I am still using the original regulator.. according tho that shop and the guy there I have about the max you can do with their parts

I'm impatient. I got mine from Auto Zone and had it swapped the next day. No issues.

I made the mistake of taking one apart for a rebuild,getting side tracked and not getting back to it right away and got the spacers mixed up. Anybody got the dimensions on the spacers and placement?

I am a little confused. My alternator died so I bought a kit to rebuild it. However, after installing it, it still was not producing voltage so I replaced it with a 250 amp Powermaster unit from Summit. Here is why I'm confused. I thought my alternator was a CS144 but the wiring harness could not be plugged in. The CS130 alternator I purchased fit exactly as the original and the factory connector plugged into it as it should. Did you have to change the connector to be able to plug it into your CS144 unit as the connectors are a totally different shape?

CS130 and CS144 should have the SAME connections. I did a CS144 upgrade on my old 89 which had a CS130.. direct connection..

Maybe you bought a different CS144 setup.. there are some different ones out there
