Electrical System (16). This indicator illuminates when there is a malfunction in the electrical system. The system volt-
9.
age is too high for normal machine operation or the system voltage is too low for normal machine operation.
a.
If the electrical loads (air conditioning and/or lighting) are high and the engine speed is low, then increase the
engine speed. This will generate more output from the alternator. If the alert indicator for the electrical system
turns off within 1 minute, the electrical system is operating normally. Overload can occur during periods of low
engine speeds.
b.
Revise the operating cycle in order to avoid overloading the electrical system. Overloading the electrical system
could result in discharging the batteries.
c.
Reducing loads will also help. Use the medium fan speed instead of the high fan speed.
d.
If this procedure does not cause the alert indicator to turn off, stop the machine and investigate the cause of the
fault. Refer to Troubleshooting Introduction (WP 0008 00).
