Lol, yep.

Some alternators rectify the stator Y connection by adding two more diodes, good for roughly 5 amps in my experience.

Back from the alternator shop with my 94 amp 12si wye wound alternator($65.00). After reading all of the reply's, links and info from other web sites , I have a plan. The 12si will go back in for now. The cs130 is out the window. While the folks that re-manufacturer these units have helped some or the heat issues that were common to the cs130 , that issue still remains. At this point doing what is necessary to install the cs144 seams to be the best long term solution. Putting the 12si in for now will give me time to find the best way to mount and wire the cs144.
As always Thanks for all your help . Jim H

The heat issues with the CS130 resulted from the rectifier being attached to the case with heat sink compound. the case could not dissipate the heat very well and led to early rear bearing failure. As i noted in the previous post the reman folks were aware of these issues and took corrective action, including using a larger 10mm bearing vers the original 8mm. Ibelive that their were some case mod also.
This was just one of the reasons that I decided to skip the 130 and move to the 144.

Rebuilt thousands of cs130's and they have to have heatsink compound on the rectifier. The original rear bearing was indeed too small.

As to the subject of longevity, I doubt if anyone on here puts enough miles on their H-body "toys"to ever actually wear out an alternator.
