here’s w hat to do:
A . Inspect the green w ire that
leads from the key sw itch recepta­
cle to the plastic term inals show n

nals together to ensure a good
connection. N ow test if the engine
w ill stop w hen the key sw itch is
m oved to the “O FF” position. If the
engine doesn’t stop, proceed to
the next step.
B . W hile the engine is running,
unplug the receptacle from the
back of the key sw itch.
C . P lace one end of a jum per w ire

the receptacle socket that the
green w ire goes into. Touch the
other end to the m ounting screw at
