Rodbolt, any suggestions on this Yamaha alarm problem?

Yamaha Alarm problem,
I have a 2000 Yamaha 115HP 2 stroke which is sounding an alarm and going into limp mode. The alarm does not sound with the engine off and ignition switch on. After my boat technician concluded the oil control module was faulty. He suggested and I agreed to convert the engine to premix, as he stated his conversion would remove the entire oil injection system including the oil control module. Well, I will not say the conversion was a mistake but it was unnecessary because the alarm and limp mode problem continues. The technician checked the overheat system by temporarily disconnecting the overheat sensors while the alarm and limp mode were activated with no change thus concluding the problem is not overheat related. Also all the dash gauges were temporarily disconnected thinking a gauge may have been shorting with no correction noted. He now thinks the problem maybe the cdi but he would not rule out a short somewhere in the wiring system.
Can I test the cdi unit by unplugging the limp mode wire? Or is there another way to test the cdi short of replacement?
Does anyone know which wire/s going into the cdi set the limp mode? Any ideas would be appreciated.

when how are you running it when the alarm triggers?
did your monose duplicate it or just dupe you?

Running the engine at idle speed with ear muff style water supply. The alarm will trigger immediately and the limp mode will set within a few minutes. All testing is performed between alarm set to limp mode. Than the motor is shut off and restarted.

first thing.
NO FREAKING LIMP FREAKING MODE.
its RPM reduction and IT ONLY WORKS above 2000 RPM.
your MONOSE has messed you up.
you can get an audible for low engine tank level.overtemp or low battery level,
super easy to check as the horn has 12V on it all times the key is on and either the module or the temp switchs control it.
that or a monose has hooked together the gray wires under the hood.
no LIMP mode, simply NONE.
IF an alarm is set that ALSO incudes RPM reduction you get the both SIMULTANEOUSLY.
take my advice.
find a real dealer with real techs that can show you school certificates,dated, from Yamaha.
if not go on up the street.
