15.5. The PTO switch is located on the right console
behind the key switch. This switch is part of the
start circuit, PTO run circuit, and reverse safety
circuit.
See Figure 15.5.
- The first set of terminals are in the start circuit. The
orange/white wire connects to the brake switch and the
orange/black wire goes to the neutral switches. The
PTO switch needs to be in the off position to start the
unit.
-The second set of terminals are part of the reverse
safety circuit. They consists of yellow/black wire con-
necting to the terminal "30" of the PTO relay and the
yellow/white wire which connects to terminal "87" on
the brake relay and neutral switches.
-The third and final set of terminals, PTO run circuit,
consists of blue wire from the reverse safety switches
and a red wire from the run line.
NOTE: If you are checking for power at the PTO
switch, you should have 12 volts at the red wire
and no voltage at the blue wire with the PTO
switch turned off. With the PTO switch on you
will have 12 volts at both the blue and red wires.
Be sure all other condition are being meet for the
PTO to run properly.

15.6. The KEY SWITCH is located on right console in
-There was a midyear change to the key switch. Units
with serial number before 1F014G20062 should have
key switch 725-04019 (Delta switch number 6900-31P)
and Harness 725-04170. When the old key switch is
turned to the start position it doesn't energize the fuel
shut off solenoid. This will not allow fuel to flow to the
carburetor while the engine is cranking. To correct this,
there is a new key switch (725-04228) and a harness
adapter (725-04229). This is available in kit 759-04058
(service advisory CC-451)
-A new wiring harness 759-04170A should be on all
models with serial numbers above 1F224G20001.
These models will NOT need the harness adapter
(759-04058) and will already have the proper key
switch.
-To check for the proper key switch perform the follow-
ing test.
Turn key to OFF position and check for continuity you
should have continuity between G and M only.
Turn key to the RUN you should have continuity
between L and B.
Neutral switch
Turn and hold key in the Start position you should have
continuity between L, B, and S.
-If this is the case then you have the most current
switch. The old key switch is usually identical to the
new switch. The difference being that the old switch
when turned to START would have continuity between
B and S only.
