Troubleshooting
CAUTION
Remove all jewelry, especially rings and
watches, before doing any electrical trouble-
shooting or testing. Also, disconnect the battery
cables unless the test requires battery voltage.
For effective troubleshooting and repairs, you must
have a good understanding of the electrical circuits and
components used on this machine (see electrical
schematics and wire harness drawings in Chapter 10 −
Electrical Drawings).
If the machine has any interlock switches by−passed,
reconnect the switches for safety and efficient trouble-
shooting.
NOTE: .Check the InfoCenter Display for possible op-
erator advisories or faults whenever diagnosing ma-
chine electrical problems.
Operator Advisory Screen
If one or more Toro Electronic Controller (TEC) inputs
are not in the correct position to allow certain machine
operations, or are malfunctioning, the fault indicator will
illuminate and an advisory screen will appear on the
InfoCenter Display (Fig. 22). Each advisory screen has
three elements: the advisory number/code, the advisory
description, and the advisory qualifier.
An advisory qualifier denotes the condition(s) that
triggered the advisory and provides instruction on elimi-
nating the advisory. An operator advisory may involve
one or more advisory qualifier. Typically, an advisory can
be eliminated by changing the position of the operator
control(s) referenced by the advisory qualifier. Once the
first qualifier displayed is satisfied, any additional quali-
fiers that remain to be satisfied will appear in the opera-
tor advisory screen individually.
NOTE: If a machine fault occurs during machine opera-
tion, the InfoCenter fault indicator will blink to notify the
operator (see Faults Screen in this chapter).
