Notes:1. Nomenclature: The Cyrillic letter “Г” transliterates (Russian-to-Latin) to “G” or “L” or “T.” Thus we
see Г-414 or G-414 or L-414 or T-414, all the same part.2. Cannot use Г-424 Alternator with discharged battery or without battery.3. MB-750 = MW-750, MB-750M = MB-750M4. The frame (case) of the Г-11/Г-11A generator is positive (positive-ground).5. Γ-414 Generator: P/N: 750181 6-Volt (negative ground), whereas P/N: 750181-A (positive-ground) for
fitting Г-11A’s into early K-750’s.

Alternators have progressed in output voltage and power, From the Г-11 (G-11) generator of 6-Volts/45-Watts in 1941,
the Г-11A in 1952, the Г-414 6V/65 W in 1957, the Г-424 of 12V/150W in 1974, the 14.3771 of 12V/500W in 1998.5,
to the present-day Nippon-Denso alternator of 12-V/770W.
