Toro Electronic Controller (Tec) - Toro Reelmaster 7000-D Service Manual

Toro Electronic Controllers (TEC)
Reelmaster 7000−D machines use a Toro Electronic
Controller (TEC) to control electrical system operation.
The controller contains a microcontroller that monitors
the condition of various switches and senders (inputs).
The controller then directs electrical power to control ap-
propriate machine functions (outputs) based on the in-
put conditions. The controller is attached to a bracket
under the operator seat (Fig. 31).
Logic power is provided to the controllers as long as the
battery cables are connected to the battery. A 2 amp
fuse (F−D1) provides circuit protection for the logic pow-
er to the controller.
The electrical power for controller outputs is provided
through three (3) connector terminals (PWR 2, PWR 3
and PWR 4). Three (3) 7.5 amp fuses (F−A1, F−B1, and
F−C1) provide circuit protection for the controller out-
puts.
The TEC monitors the states of the following compo-
nents as inputs:
