Fellow Yanmar owners,

Wonder if you might have experience with an issue that I'm having. All of a sudden, I can't get my engines to synchronize. Now, when I press the "sync" button, the red light on the throttle control briefly flashes, but nothing happens. Up until this past weekend, when I pressed the sync button, the red light on the throttle control would light and stay lit, and I would get an "S" on both engines' LCD displays, then, when the RPMs were close, the computer would take over and the "S" on the LCD displays would reverse out.

Now, the red light on the throttle control briefly flashes, and no "S" appears on the LCD displays.

Has anyone run into this problem? Any ideas?

Thanks!
--Ian

Hi Ian
dont know a lot about linked engines but
as most (computer people would say) have you powered down the mains,ie disconnect the batteries that may allow it to re boot.
good luck
