10.7. Each park switch contains two sets of contacts.
One set of contacts in normal closed (N.C.). The
other set of contacts is normally open (N.O.).
• The orange wires (one with black trace on the
right side, one with a white trace on the left side)
are in the starter inhibit circuit. They pass power
through the normally open set of contacts only
when the lap bars are in the "Start" position,
depressing the plungers and closing the con-
tacts.
• The yellow and green wires are in the magneto
ground circuit. When relay #1 is energized by
the application parking brake, the normally
closed contacts will complete a ground path to
the magneto when the lap bars are moved from
the "Start" position, releasing the plunger and
closing the contacts.
10.8. The reverse safety switches are located on the
control housing, accessible by removing the left
and right control consoles. (see previous sec-
tion)
10.9. Each reverse switch is located "down-stream" of
the PTO switch. They are normally closed
(N.C.). If the contacts of both switches are
opened (lap bars in non-forward position) power
is interrupted to the PTO clutch, stopping the
blades. See Figure 10.9.
Figure 10.9
10.10. The three relays are positioned under the right
side control console. See Figure 10.10.

Terminal A: 2 yellow wires. One goes to the
magneto, the second goes to the M terminal on
the key switch.
Terminal B: red wire, white trace. Energizes
windings when parking brake is applied.
Terminal C: 2 yellow wires with white traces.
Each leads to the N.C. terminal on one neutral
switch via terminal E on the PTO switch. If either
lap bar is moved from the "start" position (notch)
while the relay is energized (brake applied) ter-
minal C will have continuity with terminal A, pro-
viding a ground path to the magneto, turning off
the engine.
Terminal D: Green wire. Constant ground to
windings
Terminal E: Yellow wire with black trace. Con-
nects to terminal A on relay 2. Terminal E con-
nects to terminal A when relay #1 is not
energized.
