  • 1988 Yamaha V6 ExcelXG constant alarm

    Hi all, Please be gentle with me as this my first post..... I'm hoping the collective wisdom in here can give me a few suggestions on how to diagnose & fix a issue with the above. I've posted this in another forum and didn't get much of a response so......

    At the dock last weekend on start up I got a buzzer alarm. What's weird is that it started and ran fine with no alarms the day before on the muffs. The VRO is disconnected and I premix, so it can't be the oil alarm. The fuel tank has no sender, so low fuel has never been a issue before. The alarm sounded continuously right away so it couldn't be a overheat issue? Could it? Water pump seemed to be working just fine, nothing running hot....however..... I did notice the choke toggle "stick" a little (as in it didn't flick back to off straight away as usual) and the ignition action was also a little "stiff". Also, my deadmans lanyard has never worked, since I've had the boat (I know, I know, get it fixed). Could this be causing problems? I'm guessing the Ignition/choke switch is original, its one where the ignition, choke toggle and deadmans are all arrayed vertically one under the other on the same panel roughy 4" x 6"

    Any way i can test the ignition/choke switch/deadmans switch? Or just swap it out for a new one? Appreciate any input. Thanks in advance

    Edit: Is there any reason why a low oil warning would randomly start out of no where when the VRO has been disconnected for months?? Something grounding in the old VRO wire harness?? Clutching at straws here.
