Pto Switch - Toro Reelmaster 5210 Service Manual

PTO Switch

The PTO switch is mounted on the control panel and is
pressed to allow the cutting units to operate. An indicator
light on the switch identifies when the PTO switch is en-
gaged.
Testing
1. Before disconnecting the switch for testing, the
switch and its circuit wiring should be tested as an ECM
input with the Diagnostic Display (see Diagnostic Dis-
play in the Troubleshooting section of this chapter).
2. If the Diagnostic Display verifies that PTO switch and
circuit wiring are functioning correctly, no further switch
testing is necessary.
3. If the Diagnostic Display determines that PTO switch
and circuit wiring are not functioning correctly, test PTO
switch as follows:
A. Remove control arm covers to gain access to
PTO switch (see Control Arm Disassembly in the
Service and Repairs section of this chapter).
B. Make sure ignition switch is in the OFF position.
Disconnect harness electrical connector from the
switch.
C. 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. The PTO switch terminals are
marked as shown in Figure 28. The circuitry of this
switch is shown in the chart below. Verify continuity
between switch terminals.

D. Replace switch if necessary.
E. If switch tests correctly and circuit problem still
exists, check wire harness (see Wiring Schematic
and Circuit Drawings in Chapter 9 -- Electrical Dia-
grams).
F. Connect harness electrical connector to the PTO
switch.
G. Install control arm cover to machine (see Control
Arm Assembly in the Service and Repairs section of
this chapter).
