Multimeter The multimeter can test electrical components and cir- cuits for current, resistance, or voltage. NOTE: Toro recommends the use of a DIGITAL Volt– Ohm–Amp multimeter when testing electrical circuits. The high impedance (internal resistance) of a digital me- ter in the voltage mode will make sure that excess cur - rent is not allowed through the meter.

Troubleshooting For effective troubleshooting and repairs, you must have a good understanding of the electrical circuits and CAUTION components used on this machine (see Electrical Sche - matics in Chapter 8 – Electrical Diagrams). Remove all jewelry, especially rings and If the machine has any interlock switches by–passed, watches, before doing any electrical trouble- shooting or testing.

Page 100: Neutral Switch
Neutral Switch The neutral switch is located on the top side of the piston (traction) pump (Fig. 7). The switch is closed when the traction pedal is in the neutral position and opens when the pedal is depressed in either direction (forward or re- verse).
Page 101: Headlight Switch
Headlight Switch The headlight switch is located on the dash panel (Fig. 10) and is used to turn the headlights on and off. Testing 1. Make sure ignition switch is off. Locate headlight switch and unplug wire harness connector from switch. 2.
Page 102: Cruise Control Switch
Cruise Control Switch The cruise control switch is positioned on the dash panel above the ignition switch (Fig. 12). This switch ener- gizes the cruise control coil to allow the operator to main- tain a constant ground speed. Testing 1. Make sure ignition switch is off. Locate switch and unplug machine wire harness connector from switch.
Page 103: Brake Pedal Switch
Brake Pedal Switch The brake pedal switch is mounted on the frame under the floorboard (Fig. 15). The brake pedal switch pre- vents the cruise control coil from being energized when the brake pedal is pushed. Testing 1. Make sure ignition switch is off. Locate switch and unplug wire harness connector from switch.
Page 104: Temperature Sender
Temperature Sender The temperature sender is located near the alternator on the water flange attached to the engine cylinder head (Fig. 17). There is a blue wire attached to the terminal of the sender. Testing 1. Lower coolant level in the engine and remove the temperature sender from water flange.
Page 105: Indicator Lights
Indicator Lights High Temperature Warning Light If the engine coolant temperature rises to approximately F (104 C), the high temperature light should come on when the normally open temperature sender closes. To test the high temperature warning light and circuit wir- ing, start the engine and ground the blue wire attached to temperature sender located on water pump housing (see Temperature Sender in this Chapter).
Page 106: Traction Speed Sensor
Traction Speed Sensor The traction speed sensor is attached to the right side rear wheel motor (Fig. 21). The sensor provides ground speed information for two (2) options: the Pro Control Electronics and the speedometer kit. It uses a magneti- cally based, Hall Effect integrated circuit.
Page 107: Accessory Solenoid
Accessory Solenoid The accessory solenoid provides a current supply to the spray system and optional accessories (e.g. foam mark- ers). The solenoid is energized when the ignition key switch is in the RUN position. The accessory solenoid is attached to the electric panel under the operator seat (Fig.23).
Page 108: Pressure Rate And Boom Actuator Switches
Pressure Rate and Boom Actuator Switches The pressure rate (increase/decrease) switch is located on the spray control console (Fig. 25). This switch along with the Manual Interface Module (or Pro Control, if equipped) changes the applied current to the PWM valve which controls hydraulic flow to the hydraulic mo- tor that drives the spray pump.
Page 109: Spray Pump, Agitation And Boom Control Switches
Spray Pump, Agitation and Boom Control Switches The spray pump (on/off), agitation (on/off) and boom (on/off) control switches are located on the spray control console (Fig. 27). Testing 1. Make sure ignition switch is off. Remove console panel, locate switch and unplug machine wire harness connector from switch.
Page 110: Master Boom (Foot) Switch
Master Boom (Foot) Switch The master boom switch is located on the floorboard of the machine (Fig. 29). This switch allows the machine operator to control the operation of all boom sections us - ing one switch. Testing 1. Locate switch and unplug wire harness connectors from switch.
Page 111: Pulse Width Modulated (Pwm) Valve Solenoid
Pulse Width Modulated (PWM) Valve Solenoid The Pulse Width Modulated (PWM) Valve which con- trols hydraulic flow to the spray pump motor includes an electric solenoid (Fig. 31). When the spray console rate switch is depressed, the available current to the PWM valve solenoid is changed.
Page 112: Manual Interface Module
Manual Interface Module The manual interface module is used in conjunction with 5. If voltage change to the PWM Valve is correct, the in - the increase/decrease switch to adjust current flow to terface module, circuit wiring and increase/decrease the PWM Valve and to maintain pump rate settings when switch are functioning correctly.
Page 113: Relays
Relays The Multi Pro 5700–D uses three (3) relays that are at- tached to the electric panel under the operator seat. One of these relays is used to energize the cruise control coil. The other two relays are used in the spray system in conjunction with the master boom (foot) switch to turn the spray booms on and off.
Page 114: Glow Relay
Glow Relay The glow relay is attached to the electric panel under the operator seat (Fig. 36). When energized, the glow relay allows electrical current to the engine glow plugs. NOTE: Prior to taking small resistance readings with a digital multi meter, short the meter test leads together. The meter will display a small resistance value (usually 0.5 ohms or less).
Page 115: Fuel Stop Solenoid
Fuel Stop Solenoid The fuel stop solenoid must be energized for the engine to run. It is mounted to the injection pump on the engine (Fig. 37). In Place Testing NOTE: Prior to taking small resistance readings with a digital multimeter, short the test leads together. The me- ter will display a small resistance value (usually 0.5 ohms or less).

Page 117: Fuel Pump
Fuel Pump The fuel pump is attached to the frame just outboard of the fuel injection pump (Fig. 40). DANGER Because diesel fuel is highly flammable, use cau- tion when handling it. Do not smoke while testing the fuel pump. Do not test fuel pump while engine is hot.
Page 118: Fusible Link Harness
Fusible Link Harness The Multi Pro 5700–D uses three (3) fusible links for cir- cuit protection. These fusible links are located in a har - ness that connects the starter B+ terminal to the main wire harness (Fig. 41). If any of these links should fail, current to the protected circuit will cease.

Service and Repairs Suction Dampener The suction dampener is mounted to the suction line at the spray pump (Fig. 2) and is used to dampen suction pulses to smooth suction flow. During normal pump op- eration, the suction dampener diaphragm will move. IMPORTANT: Make sure to neutralize and remove chemicals from pump and hoses before loosening and removing spray system components.
Page 135: Pressure Dampener
Pressure Dampener The pressure dampener is mounted to the pressure line at the spray pump (Fig. 4) and is used to smooth system pressure pulsation. Adjust air pressure on the pressure dampener from 12 to 15 PSI (.83 to 1.03 bar). IMPORTANT: Any fluid in the pressure dampener will include spray system chemicals so take neces- sary precautions when working with the dampener.
