1993 mercury 60 hp beeping problem (really)

[D.D.E.]

Thanks everyone, I have several reply's and will get to work checking and trying the suggestions. This is a great site, and good people willing to help.
Thanks again, Dennis

UPDATE;
I disconnected one of the blue wires for float in injector oil tank. beeps stopped.
Tack did not start working again, and i am still wondering why the key would not shut the engine down a couple times.

I ran a direct ground wire from battery to shift, throttle control. no luck.
