    The multimeter can test electrical components and cir- cuits for current (amps), resistance (ohms) or voltage. Obtain this tool locally. 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.

  • Page 59: Troubleshooting

    Troubleshooting For effective troubleshooting and repairs, there must be CAUTION a good understanding of the electrical circuits (see Chapter 6 -- Electrical Diagrams) and components used on this machine. Remove all jewelry, especially rings and watches, before doing any electrical trouble- If the machine has any interlock switches by--passed, shooting or testing.

Turn around position proximity switch is out of adjustment (sweeper not directly behind tow vehicle). Transport position proximity switch is out of adjustment (sweeper directly behind tow vehicle).
  • Page 61 Problem Possible Causes Sweeper does not lower. Control module has timed out due to 30 minutes of inactivity. Hopper safety support is installed on lift cylinder. Diode D1 is faulty. Down Float Latch relay or circuit wiring is faulty. Down Latch Release relay or circuit wiring is faulty. Solenoid valve coil (SV2) or circuit wiring is faulty.

  • Page 62: Safety Interlock System

    Safety Interlock System CAUTION Do not disconnect the Pro Sweep proximity switches or dump beeper. They are for the oper- ator’s protection. Check operation of the switches and beeper daily to make sure the in- terlock system is operating correctly. If any switch or the beeper is not operating properly, adjust or replace it before operating the sweep- The Pro Sweep safety interlock system ensures the fol-...

When testing electrical components for continu- ity with a multimeter (ohms setting), make sure that power to the circuit has been disconnected.

  • Page 65: Dump Beeper

    Dump Beeper The dump beeper sounds to notify the operator and by- standers when the sweeper is raised for the hopper dump function. The beeper is attached to the frame in front of the RH wheel (Fig. 6). Testing 1. Position sweeper on a level surface with dump hop- per lowered.
