Diodes - Toro Workman HDX Service Manual

Diodes

A diode is used for starting circuit protection from voltage
spikes that occur when the starter solenoid is de--ener-
gized.
If a vehicle is equipped with the optional High Flow Hy-
draulics Kit, an additional diode is used for circuit protec-
tion from voltage spikes that occur when the Kit hydraulic
solenoid is de--energized.
If a vehicle is equipped with the optional light kit that in-
cludes flashers, two (2) additional diodes are used for
flasher circuit logic.
These diodes plug into the vehicle wiring harness at vari-
ous locations (see appropriate vehicle electrical sche-
matic and wire harness drawings in Chapter 11 --
Electrical Drawings).
Testing
The diodes can be individually tested using a digital
multimeter (diode test or ohms setting) and the table to
the right.
