Electrical System (35) - This indicator illuminates when there is a malfunction in the electrical system. The system voltage is too high for normal machine operation or the system voltage is too low for normal machine operation.If the electrical loads (air conditioning and/or lighting) are high and the engine speed is low, then increase the engine speed. This increase 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.Revise the operating cycle in order to avoid overloading the electrical system. Overloading the electrical system could result in discharging the batteries.Reducing loads will also help. Use the medium fan speed instead of the high fan speed.If this procedure does not cause the alert indicator to turn off, stop the machine and investigate
