7-14 ACCESSORIES
If the switch is defective and requires re-
placement, proceed to Section 7-6, Single
Lever Shift Box Service.
7- Cranking System Inoperative
If the starter fails to crank the engine,
check to be sure the throttle lever is in the
idle position. If the throttle is advanced
more than 1/4 forward, the cutout switch
attached to the armature plate will open the
circuit to the starter solenoid. If the crank-
ing system fails to operate the starter pro-
perly when the throttle lever is in the IDLE
position, check the 20-ampere fuse between
the ingition switch BAT terminal and the
ammeter GEN terminal.
If the starter operates in full throttle
(which it should not do), check for a short
between the two white leads in the shift box
wiring.
Further problems in the cranking system
may indicate more serious problems. See
Chapter 6, starter motor sections.
DISASSEMBLING
GOOD WORDS
On Johnson units, a friction screw is
installed in the bottom side of the shift box.
This screw allows friction adjustment of the
throttle handle. This arrangement prevents
the throttle handle from "creeping" after
the operator releases his grip on the handle.
The box has a maximum advance screw.
The adjustment is made through movement
of a screw in the warmup lever. If the
engine shuts down when the throttle lever is
moved back, then an adjustment must be
made at. the engine. This is accomplished
through an adjustment knob at the engine.
Movement of this knob will actually
lengthen or shorten the cable slightly for
proper operation.
1- Remove the attaching screws; pull
the shift box clear; and then disconnect the
shift wire under the dash. Remove the
screws from the back side of the box.
2- CAREFULLY separa te the two
halves. Check the shift box for salt water
corrosion, worn bushings, and general condi-
tion.
Throttle Cable
Notice how the throttle cable enters the
throttle half of the shift box through the
idle link. On the top side of the shift box,
