Sorry. Premature send finger press. Complete text: Any time a problem starts up that has not existed before, adding additional relays and wires is merely a bandaid. Lots of wires in the older boat are non-tinned wire and rot out from exposure to water that wicks up under the insulation and gradually turn the copper conductors to green dust. The big diagnostic trap to be aware of is that voltage measurements may sometimes look correct but the oxidized conductor in the circuit being measured cannot carry any useful current.
Another source of problems is the plug/socket assemblies in the harnesses. Very useful for the builder but often a source of continuing problems as they are generally located in an inhospitable part of the boat and easily develop problems. I frequently simply remove the connectors and butt-splice the individual wires together. Lots of places to find causes for electrical mysteries. Rich Knowles Indigo.

I had exact same symptom on a previous boat (Yanmar 2gm20f). Apparently, the wiring from the starter switch to the starter solenoid is NOT QUITE adequate to always energize the solenoid. It can be fixed by adding an additional relay. See the following link for details. http://www.cruisersforum.com/forums/f54/yanmar-starter-is-intermittent-9085.html Cheers, Mike C&C30 mk II Echappe From: Indigo [mailto:ind...@thethomsons.us] Sent: Friday, September 20, 2013 8:52 AM To: cnc-list@cnc-list.com Subject: Stus-List Yanmar 3GMF Starting Problem Recently Indigo has developed what is currently annoying problem, but could become more serious. After turning the key (and getting the low oil-pressure buzzer), when I press the starter button, absolutely nothing happens. I press it again, and it usually starts right up. Occasionally more pushes on the button are required. Is the remedy going to be simply replacing the push-button ignition switch or am I likely facing something more to fix?
