adjusting a dual station control

i have a Yamaha dual station control... when i go to the upper station..
and put the starboard motor in forward .. and give it gas, it sets off the
alarm..i then go to the lower station..move the shifter around.. try it again..it now works.. how do i adjust it...and where do i adjust it..

[jb123]

does the gauge show an alarm or is it the keyswitch ?

it seams to be the keyswitch

[jb123]

does it do it with BOTH motors? try running one then the other to isolate. THEN unhook the main harness and run, see it it IS the keyswitch.

i have isolated it, it's the starboard lower shifter causing the problems...the lower
shifter does not seam to be centered in the neutral position, I'm trying to find out how to adjust the actuator,and if that is where you do the adjusting.
On the dual station unit... only one station can be used.. the other is locked out....so the unit must be centered in the neutral position...
