on my Yanmar
3HM died recently, and in replacing it I came up with a Delco CS130 Series with a 105A output. The new one physicallly fits on the engine
and the belt lines up. The alternator
is interlally regulated, and is called a one-wire system. Apparently I only need to connect the Batt output and everything will work. The concern I have is that the Yanmar wiring
includes two additional wires which went to a plug
on the old alternator. One of these was to the ignition, and the other to the alternator lamp. With a one-wire alternator, will the sounder alarm
go off because the other wires are not connected? The new alternator includes a rectangular plug
with 4 pins. The source says these need not be used. Any thoughts?
