Another tiny terminal must have some voltage (no matter what flows through the bulb) Generally MOST internally controlled alternators should have some favourable voltage going to all their terminals Together with the ignition on.
Some voltage regulators uses this like a reference to control the alternator output. Frequently the brushes (as well as the rotor industry) are run via a individual set of diodes. Delco alternators have such a list of diodes, known as a TRIODE ASSEMBLY: it's 3 diodes in a single
