Has anyone every rebuilt a Lincoln cont. 4g alternator that was supposedly faulty with the diodes in the unit? I took mine almost all the way apart, and the biggest fault i seen at the moment is dirty, and the worm voltage regulator. I can't see any diodes yet, but tomorrow i will get a soldering iron to release the diode block from the unit. I don't have the money to buy a new alternator, yes i know these is the best policy. I was taught to rebuild parts by a old Vietnam mechanic who taught me, i need the cheapest route. Rent is also due with the money i have, anyways i was wondering if anyone has rebuild a 4g black 3 prong 4.6 alternator also where they acquired the parts from? Thank you.

I rebuilt two by taking junkyard alternators, disassembling, then combining the best parts onto the ones with the smoothest bearing/best rotor. Still have one on shelf for my 95 (now sold).

The diodes are usually on a plate attached to the rear housing. Output from the diodes goes to the charge output stud. They're big and require a pretty stout soldering iron to undo, and of course you need replacements. Honestly I tend to limit my alternator rebuilding to new bearings and cleaning. Beyond that its too time consuming and the parts are not as easy to obtain.
