Review YANMAR Relays Genuine Oem Engine Parts And fits MARINE

The Yanmar 127677-77330 is a marine engine relay designed specifically for use with Yanmar marine engines. This particular relay is part of the ignition system and is essential for the proper functioning of the engine. It comes with three separate relays, each serving a distinct purpose in the ignition system.

The first relay in this set, labeled as the number one relay, is a 15A coil-on-plug (C.O.P.) ignition relay. Its primary function is to supply power to the ignition coils when the engine is started. It ensures a stable and reliable ignition system by providing the necessary power to the coils.

The second relay, labeled as the number two relay, is a 30A high-current ignition relay. This relay is responsible for supplying power to the high-current components of the ignition system, such as the distributor or the cranking motor. It can handle the increased current demand during engine cranking and starting.

The third and final relay, labeled as the number three relay, is a 10A accessory relay. This relay is used to power various accessories in the engine system, such as the fuel pump, water pump, or lighting. It ensures that these accessories receive a consistent power supply, allowing them to function correctly.

The Yanmar 129927-77920 is the harness that connects the relays to the engine control module or the battery. This harness includes wiring for all three relays, as well as a ground wire, and makes installation straightforward. The wiring is color-coded for easy identification and connection to the corresponding terminals on the engine control module or battery.

These relays are designed to meet the demanding requirements of marine applications. They are built to withstand the harsh marine environment, including exposure to saltwater, UV radiation, and extreme temperatures. The housings are sealed to prevent water intrusion, ensuring a long service life even in the most challenging conditions.

In summary, the Yanmar 127677-77330 is a marine engine relay set consisting of three separate relays and a wiring harness. Each relay serves a specific function in the ignition system, providing power to the ignition coils, high-current components, and accessories. The set is designed to meet the demands of marine applications and is built to withstand the harsh marine environment.
