Review on ⚓ DB Electrical AHI0059: Yanmar Marine Diesel Alternator (Hi-Output 80 Amp) - Compatible/Replacement for 3Jh2, 3Jh3, 4Jh2, 4Jh3, 4Lh, 6Ly Engines - LR180-03C & 84150 Compatible by Dennis Black

The generator comes with no documentation or wiring diagrams. When they called the company and spoke to their tech support, they told me they don't have and don't provide that kind of documentation, nor do they offer any wiring assistance. The connection terminals on the generator are not marked in any way. Although it went into my application and my wiring harness appeared to match the alternator, it required an additional ground connection that was unmarked, was not part of my original wiring harness and without which the alternator would not function. It took me some time to figure it out myself. Even though it's sold as a marine alternator, its internal regulator gives it a charge curve that takes forever to charge any size battery pack. Anything but a boat for everyday use and this generator is not what you need.
