5. Measure the input voltage at each termi-
nal of the accelerator position sensor
coupler
b
(wiring harness end).
6. Turn the engine start switch to OFF, and
then connect the accelerator position
sensor coupler
b
.
Checking the accelerator position
sensor
1. Connect a computer to the outboard
motor and use the YDIS to display
“Accelerator position sensor 1” and
“Accelerator position sensor 2.”
NOTE:
To connect and operate the YDIS, see Chap-
ter 9, “YDIS” and the YDIS (version 1.23a or
later) Instruction Manual.
2. Check that the accelerator lever
1
con-
tacts the fully closed stopper
2
when the
remote control lever is at the fully closed
position.
NOTE:
To adjust the throttle cable, see Chapter 3,
“Adjusting the throttle cable.”
3. Check that the remote control lever is in
the fully closed position of the throttle,
and then check the output voltages of
accelerator sensor 1 and accelerator
sensor 2.
