Procedures done for this write-up may not be the best of all procedures. Others may state also their methods. It's a forum.

This may require minimal mechanical and technical skills.

Tools for the job includes your basic/common wrenches and screwdrivers, a simple multimeter (continuity/diode test), a workbench with a vice (of course), plastic hammer, soldering gun (about 100W) and soldering pump.

First, of course, is to "divorce" the alternator from the engine. For some diesels, remove the vacuum pump from the rear of the alternator.

Alternator involved is a mitsubishi 12 volts, 75 ampere married to a 4d56 turbocharged engine. Picture below shows the battery charging terminal (pointer finger)and the lamp and sender terminals (thumb).



Remove the long through-bolts and knock gently through the ears.



It also helps if you have the manual for some specific tests later on
