Some voltage regulators makes use of this for a reference to control the alternator output. Often the brushes (as well as rotor discipline) are powered by way of a separate set of diodes. Delco alternators have this kind of set of diodes, termed a TRIODE ASSEMBLY: It truly is three diodes in one
One other smaller terminal ought to have some voltage (what ever flows through the bulb) Mainly MOST internally controlled alternators ought to have some positive voltage likely to all their terminals with the ignition on.
