Ground Follow Switch - Toro ProCore 648 Service Manual

Ground Follow Switch

The ground follow switch is located on the side of the
control panel (Fig. 18). This rocker switch allows the
True Core TM ground following system to be turned on/
off. The switch is retained in position by a cap screw and
nut placed in the switch guard to prevent accidental
switch movement. In the normal, upper switch position,
the True Core TM ground following system is ON. The
True Core TM ground following system is OFF when the
switch is in the lower position.
The switch terminals are marked as shown in Figure 19.
The circuitry of the ground follow switch is shown in the
chart below. With the use of a multimeter (ohms setting),
the switch functions may be tested to determine whether
continuity exists between the various terminals for each
switch position. Verify continuity between switch termi-
nals.

The Aerator Control Module monitors the operation of
the ground follow switch. If the ground follow switch is in
the ON (up) position, the Control Module ground follow
LED should be illuminated when the ignition switch is
ON (Fig. 20). If the ground follow switch is in the OFF
(lower) position, the Module ground follow output LED
should not be illuminated.
