David,
If it ends up being your starter, the local expert in our area is Don Fontaine. He does all the local marina work and all the work for Barton and Gray, the Hinckley partnership club based in Stonington. His shop is in the velvet mill in Stonington Borough. I can email you his contact info. He rebuilt my starter and alternator two years ago. I think it was under 400 for both. Good luck!

I replaced almost all the wiring from the alternator to the panel, from the key to the push button, from the push button to the solenoid, etc... Nothing I had done so far worked (although through testing/metering everything I did fix a few other intermittent problems). I pulled the starter (two mounting bolts, and three contacts on the alternator) and took it apart. The ground brush was worn down to the point that you could see light between it and the commutator. For $60, 10 hours later a local ignition shop installed new brushes, a new solenoid, and cleaned everything up for me. While I'm glad I spent the time tracing the wiring and learning how the system works, I kind of wish I had pulled the starter straight away to bench test it.

Nothing at all when I push the start button. I ran the engine before the race and all was fine and have had no issues at all this year. Fortunately, I was able to sail the short distance to the mooring without a problem. I will be going out to the boat later to try to fix the problem and wanted to see if anyone had thoughts on the problem from personal experience. Plenty of power- batteries fully charged. I tried bridging the two batteries just to be sure and still nothing happens. Key switch on I can hear the fuel pump ticking over. I measured 12V across the start button poles, which goes to zero when pressed and my recollection is that is normal the way it is wired with the glow plug button. I have not yet measured at the starter, as that is a real PITA to get to. Everything had been working fine up until that incident. The only thing that happened during the race, (and I don’t think relevant) is that the genoa sheet got wrapped around the engine stop pull knob at one point. I checked and the cable and stop look fine, and the engine should still turn over even if it were pulled, is my understanding. It just should not start. So I am thinking either engine ground wire or starter and plan to clean both and try again. Any thoughts welcome. Thanks- Dave S/V Aries 1990 C&C 34+ New London, CT -- --- Thomas C.
