The Greensmaster machine use a Toro Electronic Controller (TEC) to manage
the machine electrical functions. The controller is a microprocessor controlled
device that senses the condition of various switches (inputs) and directs electrical
power to control the appropriate machine functions (outputs) based on the inputs.
The status of inputs to the controller as well as outputs from the controller can be
monitored with the InfoCenter display on the console. If a problem exists that
could prevent normal operation, the InfoCenter display will display an operator
advisory or fault code to assist in identifying the problem.
The TEC is attached to the battery mount inside the battery cover; refer to
Figure 33.
Before performing any welding on the machine, do the following to
prevent damaging the electrical system of the machine:
- Disconnect the machine connector from the lithium battery pack.
- Disconnect the wire harness connectors from the Toro Electronic
Controller.
Note: If the TEC is replaced for any reason, the machine software must be
updated; contact an Authorized Toro Distributor for assistance.
