Toro Electronic Controllers (TEC)
Groundsmaster 4000--Dand4010--Dmachinesusetwo
Toro Electronic Controllers (TEC) to control electrical
system operation. The controllers are attached to the
operator platform under the controller cover (Figs. 43
and 44).
IMPORTANT: Before performing welding on the ma-
chine, disconnect both positive and negative bat-
tery cables from the battery, disconnect wire
harness connector from both of the TEC controllers
and disconnect the terminal connector from the al-
ternator.Thesestepswillpreventdamagetothema-
chine electrical system.
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, engine oil pressure switch, flow divider switch,
Hi/Lowspeedswitch,hydraulic temperature sender,en-
gine coolant temperature sender, engine cooling fan
switch and optional cruise control switches (if
equipped).

solenoid coils (speed and direction), fuel pump, engine
run solenoid (hold coil), glow plug relay, start relay, high
temperature warning light, diagnostic light, audio alarm,
hydraulic 4WD manifold solenoid coil (flow divider), hy-

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).
NOTE: The TEC controllers used on the Groundsmas-
ter 4000 and 4010 are matched for correct machine op-
eration. If either of these components are replaced for
any reason, system software needs to be repro-
grammed by your Toro Distributor.
