The electrical schematics and other electrical drawings
for Workman HD series vehicles are located in Chapter
11 − Electrical Drawings.
Special Tools
Order special tools from your Toro Distributor. Some
tools may also be available from a local supplier.
Digital Multimeter
The digital multimeter can test electrical components
and circuits for current (amps), resistance (ohms) or
voltage. Obtain this tool locally.
NOTE: Toro recommends the use of a DIGITAL Volt−
Ohm−Amp multimeter when testing electrical circuits.
The high impedance (internal resistance) of a digital me-
ter in the voltage mode will make sure that excess cur-
rent is not allowed through the meter. This excess
current can cause damage to circuits not designed to
carry it.

Dielectric Gel
Dielectric gel should be used to prevent corrosion of un-
sealed connection terminals. To ensure complete coat-
ing of terminals, liberally apply gel to both component
and wire harness connector, plug connector to compo-
nent, unplug connector, reapply gel to both surfaces and
reconnect harness connector to component. Connec-
tors should be thoroughly packed with gel for effective
results.
Do not use dielectric gel on sealed connection terminals
as the gel can unseat connector seals during assembly.

Battery Hydrometer
Use the battery hydrometer when measuring specific
gravity of battery electrolyte. Obtain this tool locally.
