My truck slowly started having converter lock/unlock issues after 2.5 years of no issues. I initially removed the stock alternator because it was reading .05mv A/C voltage and that solved the lockup issues I was having. In place of the stock alternator I installed a Nations 180A alternator. 

 

Now 2.5 years later my lockup issues have slowly come back and are getting bad at 45-50mph. Today I checked A/C voltage and read .045mv on the meter. I’m wondering if anybody knows the part number for the rectifier/diode bridge to replace the Nations unit? 

W-T Ground wire mod, and the PCM protection fuse mod will cure it permanently. All these articles are in the 2nd gen electrical section.
