ACCELERATOR
GEAR
Remove the cover.
Backlash between gears must be reduced to a minimum by sliding holder; use locktite 262
to lock the three screws.
When the plastic gear is fully depressed a small backlash must remain between the gears.
When the plastic gear is released its rear portion must not exceed the pedal case.
MICRO-SWITCH
The micro-switch must deactivate the on/off solenoid when the accelerator is released; turn the
adjusting screw (shown on figure below) to adjust the micro-switch height.
POT
Remove the terminals 2 and 3 on PMC to measure resistance signal.
When the micro-switch is activated the signal must be less than 50 ohms. When the front
portion of the pedal is fully depressed the signal must be more than 4600 ohms.
To modify the resistance, turn the adjusting screw to change the micro-switch height (see
figure below).
Proceed with the same verifications after the accelerator cover is on and then connect terminals 2 and 3.
