ATG10443 One Wire Marine High Output Alternator – Fits OMC Prestolite Marine Engine 12V 78A Replacement Generator Alternator

Part Numbers: 78ATG10443

Product Description

The ATG10443 One Wire Marine High Output Alternator is a marine-grade replacement charging generator designed for OMC Prestolite marine engine applications.

This alternator provides reliable 12V 78A high-output charging performance and is designed as a direct replacement upgrade for traditional marine alternators. The one-wire charging design simplifies installation by combining the charging output and voltage regulation functions into a single connection, making it ideal for marine repower projects, fishing boats, cruisers, and recreational watercraft.

Built for harsh marine environments, ATG10443 features corrosion-resistant components, durable bearings, heavy-duty internal windings, and a reliable regulator system to provide stable charging performance under vibration, moisture, and continuous operating conditions.
