Wor k ma n MD E Page 3 - - 2 Electrical System General Information The Workman MDE uses a 48 volt DC electrical system that is an isolated circuit. The vehicle frame is not used for any ground connections. The vehicle controller monitors operator and vehicle in- puts to determine voltage to the traction motor .
Wor k ma n MD E Page 3 - - 3 Electrical System Electrical Diagrams The electrical schematic, circuit drawings and wire har- ness drawings for the Workman MDE are located in Chapter 6 - - Electrical Diagrams.
Wor k ma n MD E Page 3 - - 4 Electrical System V ehicle Operation The Workman MDE electrical system uses a 48 volt bat- tery pack, an electric traction motor , a vehicle controller and numerous other electrical components to allow ve- hicle operation.
Wor k ma n MD E Page 3 - - 5 Electrical System Special T ools Order special tools from your T oro Distributor . Some tools may also be available from a local supplier . Multimeter The multimeter can test electrical components and cir- cuits for current, resistance or voltage.
Wor k ma n MD E Page 3 - - 6 Electrical System Battery W atering Dispenser Use the battery watering dispenser when adding dis- tilled water to vehicle batteries. T oro Part Number: TOR4102 Figure 6 Battery Hydrometer Use the battery hydrometer when measuring specific gravity of battery electrolyte.
Wor k ma n MD E Page 3 - - 7 Electrical System 36/48 V olt Battery Discharge Unit The 36/48 V olt Battery Discharge Unit is recommended for quick and accurate load testing for the batteries on the Workman MDE.
Wor k ma n MD E Page 3 - - 8 Electrical System T roubleshooting CAUTION Remove all jewelry , especially rings and watches, before doing any electrical trouble- shooting or testing. Disconnect a battery cable from the battery pack to open the battery circuit unless a test procedure requires battery voltage.
Wor k ma n MD E Page 3 - - 9 Electrical System General Run Problems (Continued) Problem Possible Causes T raction motor stops during operation. Wiring to the traction motor components (e.g. main contactor , controller , traction motor) loose, corroded or damaged (see Electrical Schematic in Chapter 6 - - Electrical Diagrams).
Wor k ma n MD E Page 3 - - 10 Electrical System Battery Charger Problems Problem Possible Causes Battery charger does not turn on. AC outlet fuse/circuit breaker blown. AC outlet is faulty . V ehicle wiring is loose or damaged (see electrical schematic in Chapter 6 - - Electrical Diagrams).
Wor k ma n MD E Page 3 - - 1 1 Electrical System Adjustments Accelerator Switch Adjustment 1. Position vehicle on a level surface, turn on/off switch OFF and remove key . 2. With the accelerator pedal released, check that the distance between the head of the accelerator switch stop cap screw and the body of the switch is 5/8 inch (15.
Rev . A Wor k ma n MD E Page 3 - - 12 Electrical System Accelerator Potentiometer Adjustment (Potentiometer with Short Lever) NOTE: The following adjustment procedure should be used on vehicles that have a potentiometer that includes a short lever (Figure 14).
Wor k ma n MD E Electrical System Page 3 - - Accelerator Potentiometer Adjustment (Potentiometer with Long Lever) NOTE: The following adjustment procedure should be used on vehicles that have a potentiometer with a long lever (Figure 15.1).

Wor k ma n MD E Page 3 - - 13 Electrical System Accelerator System Calibration The accelerator system on the Workman MDE includes the accelerator pedal assembly , the accelerator poten- tiometer , the accelerator switch and the controller .
Wor k ma n MD E Page 3 - - 14 Electrical System Component T esting For accurate resistance and/or continuity checks, elec- trically disconnect the component being tested from the circuit (e.g. disconnect the harness wire connectors from the vehicle on/off switch before doing a continuity check on the on/off switch).
Wor k ma n MD E Page 3 - - 15 Electrical System Battery Discharge Indicator and Hour Meter Gauge The combination battery discharge indicator and hour meter gauge is located on the dash panel (Fig. 19). The battery indicator identifies s tate of charge of the bat- tery pack.
Wor k ma n MD E Page 3 - - 16 Electrical System V ehicle Direction (Forward/Reverse) and Headlight Switches The vehicle direction (forward/reverse) switch (Fig. 21) and headlight switch (Fig. 22) are located on the c ontrol panel. These two switches have identical logic.
Wor k ma n MD E Page 3 - - 17 Electrical System V ehicle Status Light The vehicle status light is located on the control panel (Fig. 24). During normal operation, the status light should be continuously illuminated. A vehicle electrical problem will be identified by a flashing status light.
Wor k ma n MD E Page 3 - - 18 Electrical System Supervisor Speed Limit Switch The supervisor speed limit switch is open in OFF posi- tion (key vertical) and closed in ON position (key rotated clockwise). The speed limit switch is one of several in- puts for the vehicle controller and allows the s peed of the vehicle to be limited.
Wor k ma n MD E Page 3 - - 19 Electrical System Charger Interlock Switch The charger interlock switch is located behind the char- ger receptacle plate on the front of the seat base (Fig.
Wor k ma n MD E Page 3 - - 20 Electrical System Main and Accessories Contactors T wo contactors (solenoids) are used on the Workman MDE for circuit control. The main contactor provides current to the vehicle c on- troller and is energized when the on/off switch is ON.
Wor k ma n MD E Page 3 - - 21 Electrical System 6. Replace contactor if necessary . 7. Connect electrical connections to contactor . If main contactor connections were removed, use Figure 33 as a guide for reattaching cable and wire harness connec- tions.
Wor k ma n MD E Page 3 - - 22 Electrical System Fuses There are three (3) fuses in the Workman electrical sys- tem. T wo (2) of the fuses are located beneath the steering column (Fig. 34). These fuses supply power to the fol- lowing: The upper 10 ampere fuse (F2) supplies power to the on/off switch and switched circuits.
Wor k ma n MD E Page 3 - - 23 Electrical System Fusible Links The wiring harness for the Workman includes three (3) fusible links for circuit protection (Fig. 36). T wo (2) fusible links attach to the s ame main contactor post as the main fuse. One of these fusible links (FL2) is used for the switched power circuit.
Wor k ma n MD E Page 3 - - 24 Electrical System Accelerator Switch The accelerator switch is a four terminal, two circuit switch that is located on the control pedal frame (Fig. 37). The Workman MDE uses only one of the s witch cir- cuits (terminals 3 and 4).
Rev . A Wor k ma n MD E Page 3 - - 25 Electrical System Accelerator Potentiometer The accelerator potentiometer is attached to the pedal frame under the dash (Fig. 39). This potentiometer is used as one of the inputs for the vehicle controller to command vehicle speed.
Wor k ma n MD E Page 3 - - 26 Electrical System Controller The Workman controller is secured to the rear frame un- der the controller cover beneath the cargo box (Fig.
Wor k ma n MD E Page 3 - - 27 Electrical System 1F l a s h System inoperable. T urn on/of f switch OFF , wait s everal seconds and turn on/off switch ON.

Wor k ma n MD E Page 3 - - 29 Electrical System Battery Removal (Fig. 42) W ARNING POTENTIAL HAZARD: The battery terminals, metal tools and metal ve- hicle parts could short together . WHA T CAN HAPPEN: Sparks can cause battery gasses to explode. Damaged cables could short against metal ve- hicle parts and cause sparks.
Wor k ma n MD E Page 3 - - 30 Electrical System Battery Charging When the vehicle is not in use, it is recommended to keep the batteries charged by connecting the battery charger that is included with the vehicle. The Workman MDE charger is designed to automatically charge the batteries fully without overcharging.
Wor k ma n MD E Page 3 - - 31 Electrical System Battery T esting When testing batteries in the Workman MDE, it is impor- tant to test all batteries. Proper performance of the ve- hicle depends on all batteries being in good condition. T esting will determine if one (or more) of the batteries needs to be replaced.
Wor k ma n MD E Page 3 - - 32 Electrical System Battery Storage If the vehicle will be stored for any period of time, check battery electrolyte level, adjust level if needed and then connect battery charger to vehicle. Allow charger to re- main connected to vehicle during storage to prevent bat- tery discharge and potential battery damage.
Wor k ma n MD E Page 3 - - 33 Electrical System T raction Motor Brushes The traction motor in the Workman MDE uses eight (8) brushes. T raction motor brushes should be inspected every 500 hours of operation or annually . Inspection 1. Make sure that on/of f switch is OFF .
