44553) (continued)
Electrical System: Testing the Electrical Components

1. Wire harness connectors P01 (gray) and
P50 (green)
Two color coded 12 pin wire harness connectors are attached to the controller.
The connection terminal function for the controller and the wire harness
connector pins are shown above.
The TEC wire harness connections are color coded. Make sure the
gray harness connector is installed in the gray port, and the green
harness connector is installed in the green port.
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).
Note: The Toro Electronic Controller (TEC) and the Toro Wireless Modules
(TWMs) used on the Pro Force Debris Blower are matched for correct machine
operation. If any of these components are replaced for any reason, system
software needs to be reloaded (contact an Authorized Toro Distributor for
assistance).
