Ultra Sonic Boom Switch
The ultra sonic boom switch is used as an input for the
Toro Electronic Controller (TEC) to activate the Ultra
Sonic Boom System. This switch has two (2) positions:
Automatic and Manual. The sonic boom switch is locat-
ed on the lower Operator’s control console.
If the sonic boom switch is in the Automatic position, the
sonic sensors will be activated to allow automatic move-
ment of the booms. The tips of the booms will remain at
a constant distance from the ground. The boom lift
switches can be used to raise/lower the booms when the
sonic boom switch is in the automatic position. The light
in the switch should be illuminated when the switch is in
the automatic position.
If the sonic boom switch is in the manual position, the
sonic sensors are disabled. The boom lift switches are
used to raise/lower the booms when the sonic boom
switch is in the manual position. The light in the switch
should not be illuminated when the switch is in the man-
ual position.
Testing
1. Park vehicle on a level surface, stop engine, engage
parking brake and remove key from ignition switch.
2. Remove the lower control console panel and discon-
nect wire harness electrical connector from the sonic
boom switch.
3. The switch terminals are marked as shown (Fig. 13).
The circuit logic of the sonic boom switch is shown in the
chart to the right. With the use of a multimeter (ohms set-
ting), test the switch functions for continuity between the
various terminals for each switch position. Replace
switch if testing identifies a faulty switch.
4. To test switch light, apply 12 VDC to terminal 8 (+)
and ground terminal 7 (−). The light should illuminate.
5. If the sonic boom switch tests correctly and a circuit
problem still exists, check wire harness (see Chapter 10
− Electrical Drawings in this manual).
6. After testing is complete, connect wire harness con-
nector to the sonic boom switch and install the lower
console panel.
