Re: Starter Relay
Had same problem on my Yanmar 3GM about 6-7 years ago.
Seems that voltage is lost on wiring harness. (to many connections)
Installed small, most basic auto relay.(inexpensive) Did the trick, have not had problem since.
Have told many Yanmar owners...also hear problem with some other
There is extensive info on some old sailnet threads.
