General Information
Operator’s Manual
The traction unit Operator’s Manual provides informa-
tion regarding the operation, general maintenance and
maintenance intervals for your Reelmaster machine.
Refer to the Operator’s Manual for additional informa-
tion when servicing the machine.
Toro Electronic Controller (TEC)
Reelmaster 7000−D machines use a single Toro Elec-
tronic Controller (TEC−5002) to manage machine elec-
trical functions. The TEC is attached to a bracket under
the Operator’s seat (Fig. 1).
The TEC contains a microcontroller that senses the
condition of various machine switches (inputs) and di-
rects electrical power to control appropriate machine
functions (outputs) based on the state of the inputs. The
status of inputs to the controllers as well as outputs from
the controllers can be checked with the Diagnostic Dis-
play (see Special Tools).
Because of the solid state circuitry built into the Toro
Electronic Controller (TEC), there is no method to test
it directly. The TEC may be damaged if an attempt is
made to test it with an electrical test device, such as a
digital multimeter.
IMPORTANT: Before performing any welding on the
machine, disconnect the battery cables from the
battery, disconnect the wire harness connectors
from the Toro Electronic Controller(s) and discon-
nect the terminal connector from the alternator to
prevent damage to the machine electrical system.

Engine Electrical Components
When servicing or troubleshooting the engine electrical
components, use the correct engine service manual and
troubleshooting manual. For machines with Yanmar
diesel engines, the Yanmar SMARTASSIST−Direct
electronic control diagnostics service system is avail-
able to support the error diagnosis and maintenance
services of engine electrical control devices.
