Yep, I've worked on several Yanmars. Same thing. Two owners had yard replace
starter. Problem persisted. I fixed it for an hour's time.
Pull apart the harness and Tefgel all the pins, clean and TefGel all the engine
wires and battery cables. Definitely clean both ends of the wire from starter
switch to solenoid. Think about running a dedicated wire from starter to
solenoid.
Look for gaps between the insulation and the battery cable lugs. It's a good
idea to TefGel any exposed wires at the lugs and add some heat shrink to cover
the gap. TefGel the lugs.

to
the solenoid, I think. Anyhow, it was undersized and copper instead of tinned.
Once I did those two fixes, the click stopped.

up being corrosion inside the sheathing in the battery cables. Cut back a

immediately.

the corrosion among the copper strands has enough resistance that it heats up
and sucks the battery power enough so it won't have the potential to flip the
solenoid.

>Hey everyone.
>My Yanmar 1GM10 is slowly
getting more and more difficult to start. With full battery charge, good ground
and contact, I'm finding the only way to get the starter to spin is to give
quick taps to the start button. If I hold it, it just saps the power system and
everything shuts down briefly. Is this a sign of the starter becoming
weak?
