Cutting Unit Interlock Switch; Backlap Switch - Toro Reelmaster 2000-D Service Manual

Cutting Unit Interlock Switch

This switch is normally open and closes when the cutting
units are lowered. The switch and its electrical connec-
tor are located behind and below the hydraulic manifold
on the cylinder support bracket.
1. Disconnect switch electrical connector.
2. With the cutting units lowered, check the continuity
of the switch by connecting a multimeter (ohms setting)
across the connector terminals. There should be conti-
nuity across the switch.
3. Raise the cutting units and check the continuity of the
switch. There should be no continuity across the switch
with the lift cylinder extended (cutting units raised).
4. Connect switch electrical connector.

Backlap Switch

The backlap switch is attached to the hydraulic man-
ifold. It is normally open and is closed when the backlap
knob is turn clockwise to the backlap position.
The Standard Control Module monitors the operation of
the backlap switch. If the ignition switch is in the ON
position and the backlap knob is turned to the backlap
position, the Module backlap input LED should be illumi-
nated.
Backlap Switch Test
1. Locate backlap switch on hydraulic manifold. Dis-
connect the backlap switch electrical connector.
2. Check the continuity of the switch by connecting a
multimeter (ohms setting) across the connector termi-
nals.
3. With the engine off, 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.
