Check the plugs

No' not the spark plugs.
Until about three years ago , I had a Yanmar 1GM, the earlier version of your engine, I fought a yearly battle with the control harnes that ran to the engine. It wasn't a very weather tight connection. When the plug that connects the starter switch to the started selenoid would come loose, it would do nothing. Even if it looked good, I sometimes had to clean it before I could get a response from the starter.

Conclusion... ?

As per bubb2's suggestion I read through the thread at: http://www.sailnet.com/forums/gear-m...olenoid-2.html

There was a lot of discussion about the ability of the power cable leading from the control panel back to the solenoid to provide enough current to operate the solenoid.

What a few people suggested was putting a solenoid in place between the start circuit and the starter solenoid. Whoa... wait, huh? Yeah, a solenoid to power a solenoid. Crazy I thought. I still think it is crazy, but I think it will work. Rather than spending a good chunk of change on the solenoid I figured I would first confirm or disprove this solution. I ran a 10ga wire direct from the battery, through a properly sized fuse, to a properly sized off/on toggle switch (momentary would have been better, but this is just for testing) and then 10ga to the solenoid where the start button would normally feed to.

Well what do you know? The starter spun up with no problem!! I repeated the test a couple of times (allowing proper time during test of course). Yep. it works. Unreal!

So now I'm torn between re-wiring back to the control panel or going the "stepper solenoid" route. I'll probably go the re-wiring route first since it would not cost anything to try.

Thanks again for everyone's assistance! You guys (and gals) rock!

Dan

Re: Yanmar 1GM10 won't start

Yanmar engines are NOTORIOUS for failing to start ... usually caused by corrosion in the primary circuit wiring of the starter solenoid circuit and most often corrosion in the wiring of the in-line FUSE holder that protects this circuit; but, can also be carbon build-up in the starter button switch, etc.

How to test: find/identify the battery lead from the battery that connects to the STARTER. Take an old screwdriver and 'short'/jump the Batt terminal on the starter to the center connection on the solenoid. Make sure your necktie and clothing dont get 'wrapped up' in the engine vee belts when youre leaning over the engine when 'jumping' the starter/solenoid!!!! If this engages the solenoid and the starter turns freely and with power .... repair the solenoid primary wiring circuit - keyswitch, starter button, FUSE holder, and all the connections between the starter switch and the solenoid.

Yanmar still uses non-tinned wire, non-tinned connectors and non-tinned switching components in their engine control panels, which are readily subject to corrosion (corrosion leads to high resistance and HIGH amperage draw) .... best is to 'rip it all out' and replace with TINNED wiring and components.

Re: Yanmar 1GM10 won't start

also check if you have battery selector switch could be bad and only letting enough current through to kick solenoid in had that happen to mine make sure you have continuos 12v to starter side when trying to crank
