In this video I show how to check and replace the pre-heat solenoid and the glow plugs on a Universal M3-20AC marine diesel engine. This engine is in our Catalina 28 sailboat.
Solenoid: Sierra International 23-5800
Glow Plugs: NGK (6325) Y103K
Note that the solenoid is often listed as a starter or generator solenoid, don't worry, it is also used for the glow plugs in this case.
