Take a look at Spider Marine. They have a new Hitachi 60Amp alternator for the 3GM30 listed for $120. http://www.spidermarine.com/inventory/search/make/yanmar%20marine/model-and-submodel/3gm30/year//liters/0/engine-type/any/fuel-type/any/aspiration/a -- Paul E C&C Landfall 38 S/V Johanna Ro

I have over the years had excellent luck having a local shop rebuild my alternators and starters. There are many around if you look for them. Usually small shops sometimes working out of their garage but you can tell very quickly if they know what they are doing. I think I have saved without exa

Might be a good time to consider installing a battery isolator. That will drop the effective output voltage by at least 0.6 volts, and you don't have to worry about the position of the battery switch for engine charging the batteries. 14.4 volts is not bad for alternator charging of flooded cell

Careful getting a new alternator with internal regulator if you are planning to get AGM batteries. The AGMs need slightly different charge profiles to ensure maximum longevity. The charge profile of the internal regulator won't be able to be changed. Also the internal reg won't be able to be pro

You can buy brand new yanmar alternators on ebay for ~$100. It sounds like the sensing line might just be bad. Where did you measure 15v? I would remove, clean and inspect all of the connections to the alternator. Then with the engine off verify that the voltage at the alternator matches the ba
