AET 200 shut down

[simon]

My motor shut down totally doing 4000rpm it did not even go into limp mode .
The guages went dead
I did get a flickered warning and an alarm
I could not raise the leg
Battery is fine and the power leads to the motors are fine ,I even flick over to the other battery as I have twins .
I hr later I tried again the motor fired up and appeared normal I went back up to 4000rpm for five minutes then it failed again same way this repeated three times .There where no warnings on the YDS and back at the dock I revved up to 2000 rpm it fluctuated on its own up and down .I think the ECM might have a problem any ideas?

Not familiar with the AET models but sounds like main relay on engine, the ECM would not affect trim or gauges. Check main relay or fuses which ever it has and look for loose battery connections at engine and battery.

I tested the main relay and swapped it over on the other motor same thing happened I have wiggled and pulled every cable with the motor running any other ideas
