Toro Electronic Controller (continued)
Electrical System: Testing the Electrical Components
The inputs from the key switch, parking brake latch switch, traction switch, reel
engage switch, EZ turn switch, EZ turn sensor, speed control potentiometer, and
lithium battery pack status are all monitored by the TEC.
The TEC current output to the electric motor precharge circuit, main contactor,
12 VDC outputs (InfoCenter display, EZ turn sensor, and optional hour meter),
and 5 VDC output (speed control potentiometer) are controlled based on the
inputs received by the controller.

The diagram in Figure 97
Two wire harness connectors attach to the controller with each of the connectors
including 12 pins. The connector pins are listed in the diagram.
The InfoCenter display should be used for checking inputs and outputs of the
controller used on your Greensmaster (refer to
The InfoCenter display can also be used to identify faults and operator advisories
that indicate operation issues with the machine.
Because of the solid state circuitry built into the controller, there is no method to
test it directly. The controller may be damaged if an attempt is made to test it
with an electrical test device (e.g., digital multimeter).
Figure 97
depicts the connection terminal functions of the TEC.
