ELECTRIC SHUTOFF SYSTEM
TROUBLESHOOTING
1.
Stop engine.
2.
Loosen magnetic pickup locknut (17).
3.
Turn the magnetic pickup clockwise until contact is
made with the teeth of the engine flywheel ring gear
(16).
4.
Turn the magnetic pickup counterclockwise one half
turn. This will give approximately 0.55 to 0.84 mm
(.022 to .033 in.) clearance at location (18),
between the end of the magnetic pickup and the
teeth of the flywheel ring gear.
5.
After the clearance is correct, tighten the magnetic
pickup locknut to a torque of 45 + 7 N-m (33 + 5 lb.
ft.). If the engine uses a 2301 Governor, tighten the
magnetic pickup to a torque of 70 + 14 N-m (50 + 10
lb. ft.).
NOTE: Be sure the magnetic pickup does not turn when
the locknut is tightened.
PROCEDURE C
CRANK TERMINATE SPEED ADJUSTMENT
ELECTRONIC OVERSPEED SWITCH
11. Verify button. 12. Reset button. 13. "LED" ovespeed light. 14. Seal crew plug (overspeed). 15. Seal screw
plug (crank terminate).
1.
Remove lockwire and seal from seal screws (14 and

crank terminate adjustment screw.
2.
Use a small screwdriver and lightly turn C.T. (crank
terminate) adjustment potentiometer twenty turns in
the direction of "MAX ARROW" (clockwise).
NOTE: The crank terminate adjustment screw is made
so that it can not cause damage to the potentiometer or
be removed if the adjustment screw is turned too much.
3.
Turn the crank terminate adjustment potentiometer
twelve turns in a direction opposite of "MAX
ARROW" (counterclockwise) for an approximate
crank terminate setting.
4.
Start engine and make a note of the speed at which
the starter disengages. See the SPEED
SPECIFICATION CHART for the correct crank
terminate speed.
NOTE: If setting is not correct, do Steps 5 and 6. If
setting was correct, do Step 7.
5.
Stop engine and turn adjustment potentiometer
(clockwise to increase and counterclockwise to
decrease) crank terminate speed.
6.
Start and make a note of the speed at which the
starter disengages. If needed, make more small
adjustments until the crank terminate speed is
correct.
7.
Install seal screw (15) for crank terminate
adjustment hole and install lockwire and seal.
