8. Short Circuit Wire
The short circuit and ground wires
are combined with the throttle cable
to form a unit. If either is damaged,
a new throttle cable must be
installed.
8.1 Testing
If the spark plug, ignition lead and
spark plug boot are in order, check
the short circuit wire.
– Remove the shroud, b 7.2
: Disconnect flag terminal (1) of
the short circuit wire (2).
– Connect ohmmeter to ground
and short circuit wire's flag
terminal.
– Move slide control to "STOP-O".
The resistance measured must be
about 0 Ω. If it is much higher, the
reason is a break in the wire and the
throttle cable has to be replaced,
b 8.2, b 8.3.
– Move slide control to "F" – start
position.
The resistance measured must be
infinitely high. If not, install a new
throttle cable, b 8.2, b 8.3.
