Pump Control And Neutral Engine Speed Control Switches - Toro Multi Pro 1200 Service Manual

Pump Control and Neutral Engine Speed Control Switches

The pump control and neutral engine speed control
switches are identical switches. The pump control
switch is located on the sprayer (right side) console (Fig.
15). The neutral engine speed control switch is posi-
tioned on the control console (Fig. 16).
Testing
1. Park machine on a level surface, stop engine, en-
gage parking brake and remove key from ignition
switch.
2. Locate switch, remove console panel and unplug
machine wire harness connector from switch.
3. The switch terminals are marked as shown in Figure
17. In the ON position, continuity should exist between
terminals 2 and 3. In the momentary SET position, conti-
nuity should exist between terminals 2 and 3 and also
between terminals 5 and 6. In the OFF position, there
should be no continuity between any switch terminals.
NOTE: When the switch is pressed to the momentary
SET position, terminals 5 and 6 are used to initially ener-
gize the controlled component (pump drive clutch or
cruise coil) and to set up a latch circuit through terminals
2 and 3. This latch circuit keeps the component ener-
gized through terminals 2 and 3 when the switch returns
to the ON position. Pressing the switch to OFF opens
this latch circuit and de--energizes the component.
4. Terminals 7 (--) and 8 (+) are used for the indicator
light in the switch. The light should be illuminated when
the switch is in the ON position while the controlled com-
ponent is energized.
5. Connect the harness connector to the switch after
testing. Install console panel to machine.
