Electrical System (Rev. C)
Functional Control Lever Reed Switches and Actuator
Both reed switches are normally open. They close when
the actuator comes in close proximity to the switch.
These switches are used to sense the Functional Con-
trol Lever in either the NEUTRAL or MOW position.
1. Make sure the engine is off. Disconnect electrical
connectors to both switches. Check continuity of both
switches by connecting a multimeter (ohms setting)
across the connector terminals.
2. Place the Functional Control Lever in the NEUTRAL
position. The NEUTRAL reed switch should have conti-
nuity and the MOW switch should be open (Fig. 9).
3. Place the Functional Control Lever in the MOW
position. The NEUTRAL reed switch should be open
and the MOW switch should have continuity (Fig. 9).
4. The distance between the sensing end of each
switch and the traction bracket should be 0.725 to 0.775
inch (18.4 to 19.7 mm) (Fig. 10).
5. To adjust or install actuator, place lever in neutral,
position actuator in lever until the NEUTRAL switch just
closes, and then rotate actuator two complete turns
closer to switch.
6. When adjusting switches or actuator, tighten jam
nuts 30
o
past finger tight.
7. After switch or actuator adjustment, check continu-
ity of both switches and interlock operation (See Verify
Interlock System Operation). Readjust switch or actua-
tor if necessary.

Backlap Switch (If Equipped)
The backlap switch is located on the hydraulic manifold
(when the Backlap Kit is installed). The switch is normal-
ly open and closes when the backlap knob is turned to
the backlap position.
1. With the engine off, disconnect electrical connector.
2. Check the continuity of the switch by connecting a
multimeter (ohms setting) across the connector termi-
nals.
3. Turn the backlap knob clockwise to the backlap
position while watching the multimeter. Continuity
should be made as the switch closes.
4. Turn the backlap knob counterclockwise to the mow
position while watching the multimeter. Continuity
should be broken as the switch opens.
5. Reconnect the electrical connector.
