On some other alternators the 3 wires are soldered to terminals or possibly a circuit board. Up coming remove the brushes, voltage regulator (if It truly is an internally controlled alternator: most are today), regulator diodes (the triode on Delcotrons and many others), as well as the rectifier diodes.

The stator was then eliminated and inspected for signs of rubbing as will be indicated by scratching from the marker ink. No issues were being identified.

This technique of excitation consists of a smaller sized immediate-latest (DC) generator fastened on the exact same shaft Together with the alternator. The DC generator generates a small level of electrical power barely enough to excite the sphere coils on the linked alternator to generate energy.
