Hi,

I am looking for a more efficient alternator for an old Yanmar 1GM
marine diesel. The original is 35 amp and I want to have something
between 50 and 60 amps. There is a bunch of webshops selling
replacements but they are all 35 or 40 amp alternators.

Does anyone happen to know a suitable replacement, a car alternator for
example? The best solution would be an alternator that also has the
sense-terminal for voltage control.

Elias, what ared you wanting to do?

"Efficient" ? Your lower amp alt. will produce less drag on your
engine, a higher amp takes more engine hp, to pull itself to amke more
power.

The Yanmars have may different types of alternators depending on the
application. if you can come up with a make and alternator number it
would help.

now comes the question of a battery sense terminal for voltage
control? are you wanting a system to adjust the voltage manually?

Waht is your total application and what do you want to do with it?


it helps to know....
