Bosch 0 192 033 004 External Alternator Voltage Regulator 28V 3-Terminal - Used

Bosch External Alternator Voltage Regulator — 3-Terminal, 28V (24V System)

Application: Bosch external (chassis-mount) generator/alternator voltage regulator, marked `0 192 033 004` on the cast aluminum mounting plate with a partially legible 28V 3-terminal type designation. Regulators of this Bosch series were used on 24V-system heavy-duty diesel applications including commercial, industrial and marine auxiliary/generator alternators. Specific application is not verified — this unit is sold on the strength of its photographs, cast markings, and dimensions.

Condition: Used, untested take-off. Housing is intact with no visible cracks, mounting ears are sound, and the three connector blades are present with light tarnish. Surface dirt and light oxidation on the aluminum base. No electrical or bench testing has been performed, so regulation set-point and function are unverified and no operational claim is made.

Included: One regulator with integral mounting plate, exactly as pictured. No harness, plug, or hardware.

Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
