Engine Speed Switch - Toro Reelmaster 5010- H Service Manual

Engine Speed Switch

The engine speed switch is a momentary switch that is
used as an input for the TEC controller to raise or lower
the engine speed. When the switch is depressed and
held in the forward position, the engine speed will in-
crease. Conversely, when the rear of the switch is de-
pressed, engine speed will decrease. The engine speed
switch is located on the control arm (Fig. 37).
Testing
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. Disassemble control arm to gain access to engine
speed switch (see Control Arm in the Service and Re-
pairs section of Chapter 6 - Chassis).
3. Disconnect wire harness connector from the engine
speed switch.
4. The speed switch terminals are marked as shown in
Figure 38. The circuit logic of the 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
position. Verify continuity between switch terminals. Re-
place switch if testing identifies that switch is faulty.

5. If speed switch tests correctly and circuit problem still
exists, check circuit wire harness (see Electrical
Schematic and Wire Harness Drawings in Chapter 9 -
Foldout Drawings).
6. After testing is completed, connect wire harness
connector to the switch.
7. Assemble control arm (see Control Arm in the Ser-
vice and Repairs section of Chapter 6 - Chassis).
