Toro Electronic Controllers (TEC)
Groundsmaster 4100--Dand4110--Dmachines usetwo
Toro Electronic Controllers (TEC) to control electrical
system operation. The controllers are attached to the
operator platform under the controller cover (Fig. 41).

Logic power is provided to the controllers as long as the
battery cables are connected to the battery. A pair of 2
ampfuses(F3--1andF4--1)providecircuitprotectionfor
this logic power to the controllers.

The TEC--5002 master controller monitors the states of
the following components as inputs: ignition switch,
parking brake switch, traction neutral switch, seat
switch,engineoilpressureswitch,Hi/Lowspeedswitch,
hydraulic temperature sender, engine coolant tempera-
ture sender and engine cooling fan switch. The
TEC--5002 also monitors the optional flow divider and
cruise control switches if the machine is equipped with
those options.

The TEC--5002 master controller controls electrical out-
put to the hydraulic fan drive manifold solenoid coils
(speed and direction), fuel pump, engine run solenoid
(hold coil), glow plug relay, start relay, high temperature
warninglight,diagnosticlight,audioalarmandhydraulic
traction manifold solenoid coil (Hi/Low speed). The
TEC--5002 also controls the optional hydraulic 4WD
manifold solenoid coil (flow divider) and cruise control

The TEC--5001 slave controller monitors the states of
the following components as inputs: ignition switch, cut-
ting deck lift switches, PTO switch and wing deck posi-
tion switches.
The TEC--5001 slave controller controls electrical out-
put to the hydraulic PTO and lift manifold solenoid coils.
Circuit protection for TEC--5001 outputs is provided by
three (3) 7.5 amp fuses (F4--2, F4--3 and F4--4).
Because of the solid state circuitry built into the TEC
controllers, there is no method to test a controller direct-
ly. A controller may be damaged if an attempt is made
to test it with an electrical test device (e.g. digital multi-
meter or test light).
IMPORTANT: Before performing welding on the ma-
chine, disconnect both negative and positive
cables from the battery, disconnect wire harness
connector from both of the TEC controllers and dis-
connect the terminal connector from the alternator.
These steps will prevent damage to the machine
electrical system.
