Joystick Raise And Lower Switches - Toro Reelmaster 5010- H Service Manual

Joystick Raise and Lower Switches

Two (2) micro switches for the joystick are located on the
lower mow/raise lever that is attached to the control arm.
The rear switch on the control is used to lower (and en-
gage) the cutting units and the front switch to raise (and
disengage) them. A normally open contact in the switch
closes when the joystick is positioned to either lower or
raise the cutting units. Each switch has an electrical con-
nector to make sure the normally closed contact on the
switch is not used. The raise switch has pink/blue and
black harness wires connected to it and the lower switch
has orange/white and black harness wires connected to
it. The Toro Electronic Controller (TEC) monitors the op-
eration of the joystick switches.
NOTE: To raise or lower the deck sections, the operator
seat has to be occupied. Also, to lower the cutting deck
sections, the traction speed has to be in LOW (mow)
range.
Testing
NOTE: Before disconnecting the joystick switches for
testing, the switches and their circuit wiring should be
tested as a TEC controller input with the InfoCenter Dis-
play (see Diagnostics Screen (Cutting Units item) in the
InfoCenter Display in this chapter). If the InfoCenter Dis-
play verifies that the joystick switches and circuit wiring
are functioning correctly, no further switch testing is nec-
essary. If the InfoCenter Display determines that either
joystick switch and circuit wiring are not functioning cor-
rectly, proceed with testing procedure
1. Park the machine on a level surface, engage the
parking brake, lower the cutting units and stop the en-
gine. Remove the key from the ignition switch.
2. Remove control arm covers to gain access to joys-
tick switches (see Control Arm in the Service and Re-
pairs section of Chapter 6 - Chassis).
3. Disconnect wire harness electrical connector from
the raise or lower switch that is to be tested (Fig. 47).
4. Connect a multimeter (ohms setting) across the nor-
mally open (NO) and common terminals of the switch
(Fig. 48).
5. With the joystick in the neutral (center) position,
there should be no continuity across the switch termi-
nals.
Electrical System
6. Move and hold the joystick to activate the switch be-
ing tested. There should be continuity across the switch
terminals.
7. If testing determines that joystick switch is faulty, re-
place switch.
8. If the joystick switch tests correctly and a circuit prob-
lem still exists, check wire harness (see Electrical Sche-
matic and Circuit Drawings in Chapter 9 - Foldout
Drawings).
9. After switch testing is completed, connect wire har-
ness electrical connector to the joystick switch.
10.Install control arm covers to machine (see Control
Arm in the Service and Repairs section of Chapter 6 -
Chassis).
