Multimeter
The multimeter can test electrical components and cir-
cuits for current (amps), resistance (ohms) or voltage.
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.

Battery Terminal Protector
Battery Terminal Protector (Toro Part No. 107–0392) is
an aerosol spray that should be used on battery termi-
nals to reduce corrosion problems. Apply terminal pro-
tector after battery cable has been secured to battery
terminal.
