    The multimeter can test electrical components and cir- cuits 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.
