Hi all. My Yanmar 4JH4HTE 110 HP has been flawless
for 5 years except for a starter that had to be replaced last year. When I had
to move Kristy from a slip at the boat yard to the travel lift, she wouldn’t start.
There is no power getting to the starter. I hear the floating ground solenoid
click when I push the stop button and turn the key to the glow plug position,
but not when I turn the key to “Start”. I am getting power at the 12v hubs on
the forward bulkhead of the engine room.
I’m thinking it’s probably the key switch on the Yanmar panel, but wondered if
a bad diode in the floating ground setup could keep it from starting, too. Any
I doubt the mechanic here will have a clue about how the floating ground works.
Also, my engine hour meter seems to be counting hours, but the display only
comes on intermittently. I’m guessing there’s a loose wire but haven’t found it
yet. Could this be connected somehow?
Thanks for any suggestions.
