When my starter failed, it burned causing a lot of smoke and excitement. I think the solenoid contacts stuck in the closed position causing large current flow. In any case a fire on board is a bad day. Al Liles SV Elendil C&C 37/40+ Vancouver > On Jul 10, 2018, at 7:01 AM, Gary Russell via

Hi John, I had the same symptoms on mine, at first I just made sure my batteries were on "All" at least at the beginning of the weekend and that bought me a couple years.. Then I replaced the button switch as there's no relay and it takes the brunt of the current. That bought me another year. I

I would definitely check the voltage at the starter solenoid coil coming from the button. I found on my 37+ that the voltage was very low because C&C used very small gauge wire (22 Ga.) from the engine panel to the solenoid. This resulted in a significant voltage drop (5-6 volts) which precluded

Check the ground connection first, mounted to one of the flywheel cover bolts. Clean it up and retighten. They corrode over time. If that doesn’t fix it, I’d replace the thick battery to starter wires and connectors. 36 years is a fair life for those electrical cables and they corrode inside the

Check out my video in the link below. https://youtu.be/Mp2cGDa1VOU Your symptoms sound like the brushes are going bad in the starter. That's my 1st suspect. Not hard to replace diy. It could also be the bendix(throw out solenoid) or bendix contacts in the starter. Parts are probably not availa

The clicking sound is the solenoid. It means that the push button is working, but the contacts on the solenoid may be bad. You can easily check the push button switch by shorting it out with a screw driver. You can check the starter, with the switch on, by shorting out the solenoid. I recently

Yanmar makes a relay that goes on the solenoid so that the switch is activating the relay instead of the starter. The relay requires minimal current. Easier than tracing wires or replacing wiring harnesses. Joel On Mon, Jul 9, 2018 at 9:33 PM John and Maryann Read via CnC-List < cnc-list@cnc-lis

There was a thread some time ago about intermittent starting of Yanmar engines. Our OEM Yanmar 3GM ( now 36 years old) works just fine but is occasionally exhibiting symptoms where the starter clicks when I push the button for a few tries without turning over. The starter then turns over after
