Yanmar 3GM30 battery connections
 

Hi,

I was wiring up a used Yanmar 3GM30F engine and couldn't
find a place for the negative battery connection. The
positive goes to the starter solenoid but there was not an
obvious stud for the negative cable. Usually I've seen them
bolted to the starter motor mounting bolts on engines, but
these 2 bolts look like they have never been touched for the
past 10 years of the engines life.

Is there anybody with a similar GM series Yanmar who could
recall where their neg. battery cable is connected?

Upper right on back end as viewed from front (water pump) end.
I can't remember if bolt is inserted from front or back.

I sold the boat that had the 2GM mumble years ago, but I think you
could connect the ground lead any place that appears to make a good
connection to the engine block or starter frame. A starter motor
mounting bolt sounds like a good place to me....

On my 3GM30F, the ground cable is attached to the bracket which anchors
the reverse gear cable.

Good luck

That's about where ours is.
