External Voltage Regulator 6-Wire Pigtail Denso/Hitachi Pattern - Used

External (remote-mount) 6-wire electronic voltage regulator for a DC alternator charging system. Stamped-steel zinc-dichromate housing with two slotted mounting tabs, six-position internal terminal block, and a short loomed pigtail ending in a moulded 6-way connector.

Application: not verified. The case pattern resembles Nippon Denso / Hitachi style remote regulators used on a variety of older marine diesel and generator charging systems and their aftermarket equivalents, but no manufacturer name, part number, or data plate is present on the unit, and system voltage (12V vs 24V) has not been confirmed. Identify by your alternator make/model, engine serial number, system voltage, and connector pin mapping before ordering.

Condition: used, untested take-off (grade C). Plating bright, light scratches and a small area of dried residue on the cover; terminals, insulation, grommet, and connector appear intact with no visible corrosion or heat damage. No electrical test has been performed and no output voltage or amperage rating is claimed. Sold exactly as pictured with no mounting hardware, mating connector, or documentation.

Quote is subject to final fitment confirmation by engine/transmission serial number, part number, photos, and supplier availability. 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.
