Connectors Miscellaneous

The "Computerized Test Report" that came with mine showed only "0" for each test report, so I don't know whether it was not tested or was a complete failure! The connections on the back are also different than on my Hitachi. My old one had 3 insulated terminals, this one only has 1 insulated terminal. There was no information about the wiring. And I don't see any obvious way to contact the supplier.

Great quality and direct replacement!

Was VERY happy about it a direct replacement for my 1987 Yanmar 2GM20F alternator. Got up almost immediately, no modifications required. Was also very pleased that it came with a datasheet showing the average RPM for it.

Pros
  • Technical data: alternator, voltage: 12 V, direction of rotation: clockwise, size: pluggable: Mtg. Ear 1 hole: M8-1.25 thread, Mtg. Eyelet 2 hole: 8.5 mm without thread, Mtg. Eyelet 3-hole: 8.5 mm without thread, Mtg. Ear Thickness: 14mm Clamp B+: M5-0.8 Amps: 35 Hours: 2 Pulley Class: V1 Controller: IR Fan Type: EF Short Description: Yanmar Marine & Industrial Engines 3GM
Cons
  • Doubtful

Ideal for alternators and alternators

This alternator was installed quickly and has worked great for several months. It came with a "dyno test sheet" that showed how many amps it was putting out at various RPMs. Although this alternator is sold as a 35 amp unit, it delivers about 50 amps over 3000 rpm (similar to the alternators sold as "high output" for the 1GM10). I would definitely buy another one, although I'll try my hand at repairing the diode block on my original alternator instead.
